MACRO INSTRUCTIONS

symbol:

addr7

lower 7-bit of program address

1.

JMPS

【

Format】

JMPS address

【

Function】

Jump in ROM

【

Expression】

Address is the absolute address, it can be a digital, symbol defined by EQU or the address symbol.

Combined by:

LD MBR, #k

;address=k*128+addr7

BSS addr7

Example】

JMPS MAIN

JMPS 100H

2.

VENT

【

Format】

VENT address

【

Function】

Define the entry address of sub-program and main program.

【

Expression】

Address is the absolute address, it can be a digital, symbol defined by EQU or the address symbol.

Combined by:

Same as JMPS addr11, it is combined by:

LD MBR, #k

;address=k*128+addr7

BSS addr7

This instruction should be included and must be at the beginning of the program. The first VENT denotes the

main program address and the following VENT instructions denote the entry of the sub-program. In general,

15 sub-programs can be defined at most. All the sub-programs called by CALL instruction should be defined

in VENT, or else errors will occur in assembly.
