5.2 Register Set Descriptions
The following are detailed descriptions for the IA80C152 register set. This register set is the
same for all versions of the IA80C152. There is no difference between the IA80C152 register
set and the register set for the original device.
In addition to the registers listed below, there are four banks of eight general purpose registers
(R0 through R7) which reside within internal RAM space. Selection of these register banks is
controlled through the Program Status Word (PSW).
The register descriptions are listed in alphanumeric order. The asterisk (*) indicates the register
is bit addressable.
5.2.1 A* (0E0h)
Accumulator register used for various memory, arithmetic, and logic operations.
5.2.2 ADR0,1,2,3 (095h, 0A5h, 0B5h, 0c5h)
Address match registers contain the values which determine which data will be accepted as valid
by the GSC. If using 8 bit addressing mode a match with any of the four registers will cause the
data to be accepted. If using 16 bit addressing mode a match with the pairs ADR1 and ADR0 or
ADR3 and ADR2 will cause the data to be accepted. A received address of all 1s will be
accepted regardless of whether the address mode is 16 bit or 8 bit.
