Description: If the selected condition is true, the processor initiates exception processing.
Floating-Point Status Register:
MOTOROLA
A vector number is generated to reference the TRAPcc exception vector. The stacked
program counter points to the next instruction. If the selected condition is not true, there
is no operation performed and execution continues with the next instruction in
sequence. The immediate data operand is placed in the word(s) following the
conditional predicate word and is available for user definition for use within the trap
handler.
The conditional specifier cc selects one of the 32 conditional tests defined in 3.6.2
Conditional Testing.
