Part Number: BQ79758-Q1
Other Parts Discussed in Thread: BQ79718-Q1,

Tool/software:

Hello, This is JJ

Actually, I use the BQ79718-Q1, not the BQ79758-Q1. I cannot select the BQ79718-Q1 in part number.

I have to send the SPI TX/RX into EEPROM.

BQ79718 has 3 SPI TX/RX registers, and how to send the Instruction ( 1 byte ) and 24-bit address (3 bytes) almost immediately using 3 SPI TX registers?

Best regards,

JJ

    Hi JJ,

    The BQ79718 can send 3 bytes at a time. One can configure what to send through SPI using SPI_TX1 to SPI_TX3, and SPI_EXE registers. 

    After SPI communication is complete, one can send more through SPI by changing what to write in the SPI_TX1 - SPI_TX3 registers.

    Best Regards,

    John
