TRAPcc Conditional Software Interrupt TRAPcc
Operation:
If cc, then
begin software exception processing.
Assembler Syntax:
TRAPcc
Description:
If the specified integer condition is true, normal instruction execution is suspended and software exception
processing is initiated. The interrupt priority level (I1,I0) is set to 3 in the status register if a long interrupt
service routine is used. If the specified condition is false, continue with the next instruction. See Section
A.10 for restrictions.
"cc" may specify the following conditions:
Mnemonic Condition
CC (HS) - carry clear (higher or same) C = 0
CS (LO) - carry set (lower) C = 1
EQ - equal Z = 1
GE - greater or equal N && V = 0
GT - greater than Z v (N && V) = 0
HI - higher Z v C = 0
LE - less or equal Z v (N && V) = 1
LS - lower or same Z v C = 1
LT - less than N && V = 1
MI - minus N = 1
NE(Q) - not equal Z = 0
PL - plus N = 0
VC - overflow clear V = 0
VS - overflow set V = 1
AL - always true n.a.
CCR Condition Codes: Not affected.
ER Status Bits: Not affected.
IER Flags: Not affected.
