(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
SVDE (Set Voltage Detector Enable flag)

Grouping:
Other operation
Description: Validates the voltage drop detection circuit
at RAM back-up mode when VDCE pin is
“H”.
Operation:
At RAM back-up: Voltage drop detection circuit is valid.
SZC (Skip if Zero, Carry flag)
0000101111

(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 ?
