– SPI2 shares I/O with four port G pins:
– SPI1 functions and data are handled by a register block at $0028–$002A
along with the system configuration options register 2 at address $0038. The
corresponding registers for SPI2 are at addresses $004C–$004E along with
the SPI2 control options register at address $004F. The SPI2 registers are
described in the following sections.
