Value Description
5
This bit is set to 1 when an undefined Op Code is fetched.
TRAP can be reset under program control by writing it
with 0, however, it cannot be written with 1 under
program control.
Undefined Fetch Object (bit 6).
When a TRAP interrupt occurs the contents of UFO allow
determination of the starting address of the undefined
instruction. This action is necessary since the TRAP may
occur on either the second or third byte of the Op Code.
UFO allows the stacked PC value to be correctly adjusted.
If UFO = 0, the first Op Code should be interpreted as the
stacked PC-1. If UFO = 1, the first Op Code address is
stacked PC-2.
Interrupt Enable — ITE2, ITE1 and ITE0 enable and
disable the external interrupt inputs INT2, INT1 and
INT0, respectively. If reset to 0, the interrupt is masked.
