SZC (Skip if Zero, Carry flag)

0000101111

02F

–

(CY) = 0

Grouping:

Arithmetic operation

Description: Skips the next instruction when the con-

tents of carry flag CY is “0.”

After skipping, the CY flag remains un-

changed.

Executes the next instruction when the con-

tents of the CY flag is “1.“

Operation:

(CY) = 0 ?

SZD (Skip if Zero, port D specified by register Y)

0000100100

024

–

(D(Y)) = 0

(Y) = 0 to 3

Grouping:

Input/Output operation

Description: Skips the next instruction when a bit of port

D specified by register Y is “0.” Executes the

next instruction when the bit is “1.”

Note:

Set 0 to 3 to register Y because port D is

four ports (D0–D3).

When values except above are set to regis-

ter Y, this instruction is equivalent to the

NOP instruction.

T1AB (Transfer data to timer 1 and register R1 from Accumulator and register B)

1000110000

230

–

Grouping:

Timer operation

Description: Transfers the contents of register B to the

high-order 4 bits of timer 1 and timer 1 re-

load register R1. Transfers the contents of

and timer 1 reload register R1.

Operation:

(T17–T14)

← (B)

(R17–R14)

← (B)

(T13–T10)

← (A)

(R13–R10)

← (A)

Operation:

(D(Y)) = 0 ?

(Y) = 0 to 3

02B

SZB j (Skip if Zero, Bit)

00001000j

02j

–

(Mj(DP)) = 0

j = 0 to 3

Grouping:

Bit operation

Description: Skips the next instruction when the con-

tents of bit j (bit specified by the value j in

the immediate field) of M(DP) is “0.”

Executes the next instruction when the con-

tents of bit j of M(DP) is “1.”

Operation:

(Mj(DP)) = 0 ?

j = 0 to 3
