Command Sequence
Description
ADDR 1xxx xxxx STATUS
Byte0 ... ByteN
Read data starting at ADDR. ADDR auto-increments until SPI_CSZ is
raised. Upon completion, SPI_CMD (SFR 0xFD) is updated to 1xxx xxxx
and an SPI interrupt is generated. The exception is if the command byte
is 1000 0000. In this case, no MPU interrupt is generated and SPI_CMD
is not updated.
0xxx xxxx ADDR Byte0 ...
ByteN
Write data starting at ADDR. ADDR auto-increments until SPI_CSZ is
raised. Upon completion, SPI_CMD is updated to 0xxx xxxx and an SPI
interrupt is generated. The exception is if the command byte is 0000
0000. In this case, no MPU interrupt is generated and SPI_CMD is not
updated.
