XA7-0 Peripheral Address
To access peripheral device, first write the peripheral address in this register and then perform read
or write at XDATA register. The address written in this register is output on XAD7-0 in address phase
of data access and can be latched by XALE signal.
8.1.34 Peripheral Data Register
XDATA
Read/Write
Address F8H
Value after reset: Undefined
The register content depends on PCTL: XMODE setting.
XMODE = 0: Simple IO mode
