REGISTER
DESCRIPTION
AP (00h, 08h)
Accumulator Pointer (8-Bit Register)
Initialization
This register is cleared to 00h on all forms of reset.
Read/Write Access
Unrestricted read/write.
AP[1:0]
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.
AP[7:2]
Reserved. Read returns 0.
APC (01h, 08h)
Accumulator Pointer Control (8-Bit Register)
Initialization
This register is cleared to 00h on all forms of reset.
Read/Write Access
Unrestricted read/write.
APC[1:0]–MOD[1:0]
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.
MOD[1:0]
MODULO
00
Default, no AP autoincrement/decrement
01
Modulo 2
10
Modulo 4
11
Reserved (modulo 4 if set)
APC[5:2]
Reserved. Read returns 0.
APC.6–IDS
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.
APC.7–CLR
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).
