2.5.12 SPI Slave Port
The slave SPI port communicates directly with the MPU data bus and is able to read and write Data RAM
and Configuration RAM (I/O RAM) locations. It is also able to send commands to the MPU. The interface
to the slave port consists of the SPI_CSZ, SPI_CKI, SPI_DI and SPI_DO pins. These pins are multiplexed
with the combined DIO/LCD segment driver pins SEGDIO36 to SEGDIO39 (pins 3, 2, 1 and 100).
Additionally, the SPI interface allows flash memory to be read and to be programmed. To facilitate flash
programming, cycling power or asserting RESET causes the SPI port pins to default to SPI mode. The
SPI port is disabled by clearing the SPI_E bit (I/O RAM 0x270C[4]).
Possible applications for the SPI interface are:
