JCLR Jump If Bit Clear JCLRRestrictions: A JCLR instruction cannot be repeated using the REP instruction.A JCLR located at LA, LA-1, or LA-2 of the DO loop cannot specify the program controllerregisters SR, SP, SSH, SSL, LA, or LC as its target.JCLR SSH or JCLR SSL cannot follow an instruction that changes the SP.Example:JCLR #$5,X:«$FFF1 ,$1234;go to P:$1234 if bit 5 in SCI SSR is clearExplanation of Example: In this example, program execution is transferred to theaddress P:$1234 if bit 5 (PE) of the a-bit read-only X memory location X:$FFF1 (1/0 SCIinterface status register) is a zero. If the specified bit is not clear, no jump is taken, andthe program counter (PC) is incremented by one.Condition Codes:15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0I LF I OM I T I" I 51 I SO I 11 I 10 I 5 I LIE I u I N I z v I ~ I.~ MR ......
