Accumulator Pointer (8-Bit Register)

This register is cleared to 00h on all forms of reset.

Unrestricted read/write.

Active Accumulator Select Bits [1:0]. The setting of these bits activates one of the four accumulators

in the accumulator module (A) to function as the active accumulator for arithmetic and logical opera-

tions. The setting of these bits can be automatically incremented/decremented in a modulo fashion

according to the setting to the APC register.

Reserved. Read returns 0.

Accumulator Pointer Control (8-Bit Register)

This register is cleared to 00h on all forms of reset.

Unrestricted read/write.

Modulo Bits [1:0]. The accumulator pointer autoincrement/decrement function is activated when these

bits are set to a value other than 00b. The modulo is selected accordingly when active pointer autoincre-

ment/decrement is active.

Reserved. Read returns 0.

Increment/Decrement Select. When this bit is cleared to 0, the content of AP increments after an arith-

metic or logical operation. When this bit is set to 1, the content of AP is decremented after arithmetic or

logical operation.

AP Clear. When this bit is set to 1, the content of AP is cleared to 0. This bit automatically resets to 0

after clearing the AP register. Note if the MOVE APC, Acc instruction (980Ah) causes the CLR bit to set,

the clear operation overrides other functions (i.e., the AP autoincrement/decrement does not happen).
