Basic Instructions

CAUTION

The comparison instruction regards the specified data as BIN values. Hence, if the value whose most significant bit (b15) is 1 (8 to F) is specified for comparison of hexadecimal data, it is regarded as a negative BIN value.

Example

Comparison of 4-digit HEX values

Regarded	Regarded
as -32767	as 1384
in BIN.	in BIN.

Therefore, the result is -32767 < 1384 and Y10 does not turn on.
