8-Bit Microcontroller with OTP ROM
Product Specification (V1.0) 06.01.2004
(This specification is subject to change without further notice)
43
(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 operate on I/O register.
The symbol "R" represents a register designator that specifies which one of the
registers (including 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 that selects the value for the bit located in the register
"R" and affects operation. "k" represents an 8 or 10-bit constant or literal value.
