The bit tobe tested is selected by an immediate bit number from 0-23. If the specified memory bitis not clear, the program counter (PC) is incremented and the absolute address in theextension word is ignored. However, the address register specified in the effectiveaddress field is always updated independently of the state of the nth bit. All address registerindirect addressing modes may be used to reference the source operand S. AbsoluteShort and I/O Short addressing modes may also be used.-
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 ......
