Accumulator : ACC
ACC is the Accumulator register. The mnemonics for Accumulator-Specific instructions, however, refer to the
Accumulator simply as A.
B Register : B
The B register is used during multiply and divide operations. For other instructions it can be treated as another scratch
pad register.
Program Status Word : PSW
The PSW register contains program status information as detailed in
CY
AC

RS1
BIT SYMBOL FUNCTION
PSW.7 CY Carry flag.
PSW.6 AC Auxiliary Carry flag. (For BCD operations.)
PSW.5 F0 Flag 0. (Available to the user for general purposes.)
PSW.4 RS1 Register bank select control bit 1.
Set/cleared by software to determine working register bank. (See
Note.
)
PSW.3 RS0 Register bank select control bit 0.
Set/cleared by software to determine working register bank. (See
Note.
)
PSW.2 OV Overflow flag.
PSW.1 — User-definable flag.
PSW.0 P Parity flag.
Set/cleared by hardware each instruction cycle to indicate an odd/even number of “one” bits in the
Accumulator, i.e., even parity.
NOTE
: The contents of (RS1, RS0) enable the working register banks as follows:
(0,0)— Bank 0 (00H–07H)
(0,1)— Bank 1 (08H–0fH)
(1,0)— Bank 2 (10H–17H)
(1,1)— Bank 3 (18H–17H)
