SNZP (Skip if Non Zero condition of Power down flag)
0000000011
003
11
(P) = 1
Grouping:
Other operation
Description: Skips the next instruction when the P flag is
“1”.
After skipping, the P flag remains un-
changed.
Executes the next instruction when the P
flag is “0.”
SNZT1 (Skip if Non Zero condition of Timer 1 inerrupt request flag)
1010000000
280
11
V12 = 0: (T1F) = 1
Grouping:
Timer operation
Description: When V12 = 0 : Skips the next instruction
when timer 1 interrupt request flag T1F is
“1.” After skipping, clears (0) to the T1F flag.
When the T1F flag is “0,” executes the next
instruction.
When V12 = 1 : This instruction is equivalent
to the NOP instruction.
Operation:
V12 = 0: (T1F) = 1 ?
After skipping, (T1F)
← 0
V12 = 1: SNZT1 = NOP
(V12 = bit 2 of interrupt control register V1)
Operation:
(P) = 1 ?
SNZCP (Skip if Non Zero condition of Port C)
1010001001
289
11
(C) = 1
Grouping:
Input/Output operation
Description: Skips the next instruction when the contents
of port C is “1.”
Executes the next instruction when the con-
tents of port C is “0.”
Operation:
(C) = 1 ?
SNZI0 (Skip if Non Zero condition of external 0 Interrupt input pin)
0000111010
03A
11
I12 = 0 : (INT) = “L”
I12 = 1 : (INT) = “H”
Grouping:
Interrupt operation
Description: When I12 = 0 : Skips the next instruction
when the level of INT pin is “L.” Executes the
next instruction when the level of INT pin is
“H.”
When I12 = 1 : Skips the next instruction
when the level of INT pin is “H.” Executes
the next instruction when the level of INT pin
is “L.”
Operation:
I12 = 0 : (INT) = “L” ?
I12 = 1 : (INT) = “H” ?
(I12 : bit 2 of the interrupt control register I1)
