11.0 Addressing Modes
(Continued)
11.9 MODIFIED PAGE ZERO
A subset of NSC800 instructions (the Restart instructions)
provides a code-efficient single-byte instruction that allows
CALLs to be performed to any one of eight dedicated loca-
tions in page zero (locations X’0000 to X’00FF). Normally, a
CALL is a 3-byte instruction employing direct memory ad-
dressing.
Example:
Instruction: Perform a restart call to location X’0028.
Mnemonic: RST
X’28
Opcode:
TL/C/5171–55

Program execution continues at location X’0028 after exe-
cution of a single-byte call employing modified page zero
addressing.
11.10 BIT
The NSC800 allows setting, resetting, and testing of individ-
ual bits in registers and memory data bytes.
Example:
Operation: Set bit 2 in the L register
Mnemonic: SET
2,L
Opcode:
TL/C/5171–56
Bit addressing allows the selection of bit 2 in the L register
selected by register addressing.
