Interrupt Reception Timing Chart (1/2)
(1) When one interrupt (e.g., rising edge at the INTNC pin) is used
(a) When an interrupt mask time is not set by the interrupt permission flag
#
# When the MOVT instruction or a normal instruction that does not satisfy the skip conditions is
executed at interrupt acceptance
$
$ When the MOVT instruction or an instruction satisfying the skip conditions is executed at
interrupt reception
