When chkHCR is ON, the practical device represented by HC50 is VarHCR1. Since the legal

range of deices is from HC0 to HC63, and HC50+10-1=HC59, which does not exceed the

range, HCR_ChkBit is ON.

Additional remark:

If the value (the practical device address) in S exceeds the device range, the instruction

CHKADR is not executed, SM is ON, and the error code in SR0 is 16#2003.

If the value in the operand n is not within the range between 1 and 1024, the instruction

CHKADR is not executed, SM is ON, and the error code in SR0 is 16#200B.
