18.2.3 External Interrupt Mode Register 0 (EIMOD0)
EIMOD0 is a special function register (SFR) to choose the sampling clock and with/without sampling for the external
interrupt (EXI0 to EXI7). Only one sampling clock can be chosen and it is shared for all the interrupt EXI0 to EXI7.

PG0DIV2 to
PG0DIV0
These bits are used to choose frequency dividing ratio for the sampling clock in the EXI0 to
EXI7.
000:
No dividing (Initial value)
001:
1/2 of the sampling clock source
010:
1/4 of the sampling clock source
011:
1/8 of the sampling clock source
100:
1/16 of the sampling clock source
101:
1/32 of the sampling clock source
110:
1/64 of the sampling clock source
111:
Do not use (No dividing)

PI7SM to
PI0SM
These bits are used to choose whether the input signals of EXI0 to EXI7 are detected with the
sampling clock.
0: Detected without the sampling clock (Initial value)
1: Detected with the sampling clock
The relation of the bit number and the target external interrupt:
