(SIOF) = 1

–

– Transfers the contents of serial I/O register SI to registers A and B.

– Transfers the contents of registers A and B to serial I/O register SI.

– Transfers the contents of serial I/O mode register J1 to register A.

– Transfers the contents of register A to serial I/O mode register J1.

– Clears (0) to SIOF flag and starts serial I/O.

– Skips the next instruction when the contents of SIOF flag is “1.”

After skipping, clears (0) to SIOF flag.

– Transfers the high-order 8 bits of the contents of register AD to registers A and B.

–

– Transfers the low-order 2 bits of the contents of register AD to the high-order 2 bits of the contents of regis-

ter A. Simultaneously, the low-order 2 bits of the contents of the register A is “0.”

– Transfers the contents of registers A and B to the comparator register at the comparator mode.

– Transfers the contents of the A-D control register Q1 to register A.

– Transfers the contents of register A to the A-D control register Q1.

– Clears the ADF flag, and the A-D conversion at the A-D conversion mode or the comparator operation at the

comparator mode is started.

– Skips the next instruction when the contents of ADF flag is “1”.

After skipping, clears (0) the contents of ADF flag.

– Transfers the contents of the A-D control register Q2 to register A.

– Transfers the contents of register A to the A-D control register Q2.

– No operation

– Puts the system in RAM back-up state by executing the POF instruction after executing the EPOF instruction.

– Makes the immediate POF instruction valid by executing the EPOF instruction.

– Skips the next instruction when P flag is “1”. After skipping, P flag remains unchanged.

– Operates the watchdog timer and initializes the watchdog timer flag WDF1.

– Transfers the contents of the clock control register MR to register A.

– Transfers the contents of register A to the clock control register MR.

– Transfers the contents of the voltage comparator control register Q3 to register A.

– Transfers the contents of the high-order 2 bits of register A to the high-order 2 bits of voltage comparator

control register Q3, and the comparison result of the voltage comparator is transferred to the low-order 2 bits

of the register Q3.
