specification register 0 (INTF0)
The INTR0 and INTF0 registers are used to specify the trigger mode of the INTP00, INTP01, and INTPa
(V850E/IG3 only) pins and can specify the valid edge independently for each pin (rising edge, falling edge, or
both rising and falling edges) (a = 02 to 07).
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
Caution When the function is changed from the external interrupt function (alternate function) to the
In the V850E/IF3, be sure to set these bits to 0.

to 00, and then set the port mode (V850E/IF3: n = 0, 1, V850E/IG3: n = 0 to 7).
