– Skips the next instruction when the contents of bit 2 (V12) of interrupt control register V1 is “0” and the con-
tents of T1F flag is “1.” After skipping, clears (0) to T1F flag.
– Skips the next instruction when the contents of bit 3 (V13) of interrupt control register V1 is “0” and the con-
tents of T2F flag is “1.” After skipping, clears (0) to T2F flag.
– Skips the next instruction when the contents of bit 0 (V20) of interrupt control register V2 is “0” and the con-
tents of T3F flag is “1.” After skipping, clears (0) to T3F flag.
– Skips the next instruction when the contents of bit 3 (V23) of interrupt control register V2 is “0” and the con-
tents of T4F flag is “1.” After skipping, clears (0) to T4F flag.
– Skips the next instruction when the contents of bit 1 (V21) of interrupt control register V2 is “0” and the con-
tents of T5F flag is “1.” After skipping, clears (0) to T5F flag.
– Transfers the input of port P0 to register A.
– Outputs the contents of register A to port P0.
– Transfers the input of port P1 to register A.
– Outputs the contents of register A to port P1.
– Transfers the input of port P2 to register A.
– Outputs the contents of register A to port P2.
– Transfers the input of port P3 to register A.
– Outputs the contents of register A to port P3.
– Transfers the input of port P4 to register A.
– Outputs the contents of register A to port P4.
– Sets (1) to all port D.
– Clears (0) to a bit of port D specified by register Y.
–
– Sets (1) to a bit of port D specified by register Y.
(D(Y)) = 0
– Skips the next instruction when a bit of port D specified by register Y is “0.” Executes the next instruction
However, (Y)=0 to 7
when a bit of port D specified by register Y is “1.”
–
– Clears (0) to port C.
–
– Sets (1) to port C.

–
– Transfers the contents of register A to pull-up control register PU0.
–
– Transfers the contents of pull-up control register PU1 to register A.
–
– Transfers the contents of register A to pull-up control register PU1.
