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
Value after reset: Undefined
The register content depends on PCTL:XMODE setting.
XMODE = 0 : Simple IO mode, Valid in PCI or Intel/Motorola Bus mode
