PRTxDR
21.3
The following registers are all in bank 0 and are listed in address order. An ‘x’ before the comma in the register’s address indi-
cates that the register can be accessed in Bank 0 and Bank 1, independent of the XIO bit in the CPU_F register. Registers
that are in both Bank 0 and Bank 1 are listed in address order in Bank 0. For example, the RDIxLT1 register has an address
of x,B4h and is listed only in Bank 0 but is accessed in both Bank 0 and Bank 1.
21.3.1
These registers allow for write or read access, or the current logical equivalent, of pin voltage.
The upper nibble of the PRT4DR register returns the last data bus value when read. You need to mask it off before using this
information. For additional information, refer to the
