EXECUTION
COMMENTS
EXAMPLE
SYMBOLS DEFINITION LIMITS
Program remains on line 10H (the same line) if the equation above is true:
- Input E1 = 1 and bit 7 of the address FFH of the accumulator is at 0 or data at the
address 01H of the accumulator is different of 0 otherwise, the program continues on
the next line.
hexadecimal : 01 3A 10 0C 00 09 FF 37 01 78 10 04
mnemonic :
JUMP ON BOOLEAN RESULT 3AH (resp.3BH)
JCB (resp.JNCB)
The boolean equation is presented in the form of a midterm sum:
< BN0 (AD0) * BN1 (AD1) > +< BN2 (AD2) * BN3 (AD3) > +
Jump to line LS or label is performed when the equation is true (resp. false) else
program continues on next line.
- ADN is an address into the accumulator memory or a register number.
- The PTN parameter defines :
- the address assignment (accumulator memory or register)
- the bit to test or to use.
- The bit logic state to use (0 or 1)
(ADN) value at the address ADN
PTN test parameter (see next page)
T D:accumulator memory, R:register, X:CAN0, Y:CAN1register
A Address or registre number
B bit number, test value of byte
C logic state to test ("_" to test logic 0)
S logical symbol (except the last term)
