Detailed description

−−

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 the low-order 2 bits (A1, A0) of register A.

“0” is stored to the high-order 2 bits (A3, A2) of register A.

−−

Outputs the contents of the low-order 2 bits (A1, A0) of register A to port P2.

−−

Transfers the input of port P3 to the low-order 2 bits (A1, A0) of register A.

“0” is stored to the high-order 2 bits (A3, A2) of register A.

−−

Outputs the contents of the low-order 2 bits (A1, A0) of register A to port P3.

−−

Sets (1) to 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

Y = 0 to 4

−

Skips the next instruction when a bit of port D specified by register Y is “0”. Executes the next instruction

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 port output structure control register FR0.

−−

Transfers the contents of register A to port output structure control register FR1.

−−

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

−−

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.

−−

Transfers the contents of pull-up control register PU2 to register A.

−−

Transfers the contents of register A to pull-up control register PU2.

−−

Transfers the input of port K to the least significant bit (A0) of register A. “0” is stored to the high-order 3 bits

(A3

−A1) of register A.
