SPIDATA
SPI Data. Data for SPI is read from or written to this location. The SPI transmit and receive buffers are
bits 70
separate registers, but both are addressed at this location. Read to clear the receive interrupt and write to clear the
transmit interrupt.
I2CDATA
I2C Data. Data for I2C is read from or written to this location. The I2C transmit and receive buffers are
bits 70
separate registers, but both are addressed at this location.
