The interrupt flag bit must be cleared in software before leaving the interrupt service routine and enabling
interrupts to avoid recursive interrupts.
VII.8 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.
The symbol "R" represents a register designator which specifies which one of the 64 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 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.
