instruction from “SLEP” instruction and then go to address 0x08 in IDLE mode . These two cases will set a RF
flag.
VII.7 Instruction Set
Instruction set has the following features:
(1). Every bit of any register can be set, cleared, or tested directly.
(2). The I/O register can be regarded as general register. That is, the same instruction can operates on I/O register.
operational registers and general purpose registers) is to be utilized by the instruction. Bits 6 and 7 in R4 determine the
selected register bank. "b'' represents a bit field designator which selects the number of the bit, located in the register "R'',
affected by the operation. "k'' represents an 8 or 10-bit constant or literal value.
