Application Example:

------------------------------------------------------------------------------------------------------------------------

mov

a, 0x38 ;

mov

mem, a ;

// mem = 0x38

neg

mem ;

// mem = 0xC8

------------------------------------------------------------------------------------------------------------------------

comp

a, I

Compare ACC with immediate data

Example:

comp

a, 0x55;

Result: Flag will be changed by regarding as ( a - 0x55 )

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

Application Example:

------------------------------------------------------------------------------------------------------------------------

mov

a, 0x38 ;

comp

a, 0x38 ;

// Z flag is set

comp

a, 0x42 ;

// C flag is set

comp

a, 0x24 ;

// C, Z flags are clear

comp

a, 0x6a ;

// C, AC flags are set

------------------------------------------------------------------------------------------------------------------------

comp

a, M

Compare ACC with the content of memory

Example:

comp

a, MEM;

Result: Flag will be changed by regarding as ( a - MEM )

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV

Application Example:

------------------------------------------------------------------------------------------------------------------------

mov

a, 0x38 ;

mov

mem, a ;

comp

a, mem ;

// Z flag is set

mov

a, 0x42 ;

mov

mem, a ;

mov

a, 0x38 ;

comp

a, mem ;

// C flag is set

------------------------------------------------------------------------------------------------------------------------

comp

M, a

Compare ACC with the content of memory

Example:

comp

MEM, a;

Result: Flag will be changed by regarding as ( MEM - a )

Affected flags: 『Y』Z

『Y』C

『Y』AC

『Y』OV
