The SPI-IN3~0 are used when receiving data on the serial bus. When SPI transmits only valid data
writes to the register SPI-OUT3~0, "START" will initiate the SPI data transmission from HT9580 to
FLEX
TM
decoder. After completion of the 4-byte data transfer, the "SPIFG" status bit will be set and
the internal signal "REQST" will generate a falling edge signal for NMI. The bit7 of SPI-IN3 is MSB
and bit0 of SPI-IN0 is LSB.
