Using the READ STATUS ENHANCED (78h) command prevents data contention following an interleaved die (multi-LUN) operation. After issuing the READ STATUS ENHANCED (78h) command, to enable data output, issue the READ MODE (00h) command.

NXP recommends a voltage set point = (V min + the supply tolerance). This result in an optimized power/speed ratio.2In setting VDD_HIGH_IN voltage, refer to the Errata ERR010690 (SNVS_LP Registers Reset Issue).3In setting VDD_SNVS_IN voltage with regards to Charging Currents and RTC, refer to the i.MX 6UltraLite Hardware Development Guide (IMX6ULHDG).Table 12.

Operating Ranges (continued)Electrical characteristicsi.MX 6UltraLite Applications Processors for Industrial Products, Rev. 2.2, 05/2017NXP Semiconductors 25The RTC_XTALI is used for low-frequency functions. It supplies the clock for wake-up circuit,power-down real time clock operation, and slow system and watch-dog counters. The clock input can be connected to either external oscillator or a crystal using internal oscillator amplifier. Additionally, there is an internal ring oscillator, which can be used instead of the RTC_XTALI if accuracy is not important.The system clock input XTALI is used to generate the main system clock. It supplies the PLLs and other peripherals. The system clock input can be connected to either external oscillator or a crystal using internal oscillator amplifier.Table 13 shows the interface frequency requirements.The typical values shown in Table 13 are required for use with NXP BSPs to ensure precise time keeping and USB operation. For RTC_XTALI operation, two clock sources are available.•On-chip 40 kHz ring oscillator—this clock source has the following characteristics:—Approximately 25 µA more Idd than crystal oscillator—Approximately ±50% tolerance—No external component required—Starts up quicker than 32 kHz crystal oscillator•External crystal oscillator with on-chip support circuit:—At power up, ring oscillator is utilized. After crystal oscillator is stable, the clock circuitswitches over to the crystal oscillator automatically.—Higher accuracy than ring oscillator—If no external crystal is present, then the ring oscillator is utilizedThe decision of choosing a clock source should be taken based on real-time clock use and precision time-out.4.1.5Maximum supply currentsThe data shown in Table 14 represent a use case designed specifically to show the maximum current consumption possible. All cores are running at the defined maximum frequency and are limited to L1 cache accesses only to ensure no pipeline stalls. Although a valid condition, it would have a very limited practical use case, if at all, and be limited to an extremely low duty cycle unless the intention was to specifically show the worst case power consumption.Table 13.

QTI Line Follower AppKit for the Boe-Bot (#28108)
Boe-Bot Line Following with QTIs
The QTI sensor is a close-proximity infrared emitter and receiver pair mounted on a tiny PCB. It can be used as an analog sensor to differentiate between different levels of infrared reflectivity. It can also be used as a purely digital device that returns a 1 when it detects a black line or a 0 if it detects a white background. An array of four QTI sensors used as digital devices makes an effective and flexible line-follower for the Boe-Bot robot. The QTI positions are adjustable for different sizes and types of lines. This activity demonstrates how the QTIs can be used for digital line following on a simple 3/4inch wide electrical tape course with a white background. For an in-depth look at how the QTI sensors function, and for the complete QTI Line Follower source code, see the Stamps in Class “Mini Projects” sticky-thread at the top of the Stamps in Class forum at on . For this activity, you will need to supply your own: Built and tested Boe-Bot robot #2 Philips-head screwdriver Black ¾-inch electrical tape White poster board
