RE: A85: rrca




OPCODE: RRCA

DESCRIPTION: The contents of the Accumulator (Register A) are rotated right 
1-bit position.  Bit 0 is copied into the Carry flag and also into bit 7. 
 Bit 0 is the least significant bit.

CONDITION BITS AFFECTED:
S:   Not affected
Z:   Not affected
H:   Reset
P/V: Not affected
N:   Reset
C:   Data from bit 0 of Accumulator

That is all from the Z80 CPU User's Manual.
You might want to order one from zilog.  They have an order form on their 
web site and it's free!
