Interrupt Enable Flag (IE: $000, Bit 0):
Controls the entire interrupt process. It is reset by the interrupt
processing and set by the RTNI instruction, as listed in table 4.

):
Five external interrupt signals.
External Interrupt Request Flags (IF0–IF4: $000, $001, $022, $023):
IF0 and IF1 are set at the falling
edge of signals input to
INT
0
and
INT

, and IF2–IF4 are set at the rising or falling edge of signals input to
INT

interrupt edges are selected by the detection edge select
registers (ESR1, ESR2: $026, $027) as shown in figures 12 and 13.
