Figure 10-7: Valid Edge Selection Register (Sesc0) - NEC V850E/CA2 JUPITER Preliminary User's Manual

(3) Valid edge selection register (SESC0)
This register specifies the valid edge of external interrupt requests from an external TICmn pin
(n, m = 0 to 1).
The rising edge, the falling edge, or both rising and falling edges can be specified as the valid
edge independently for each pin.
This register can be read/written in 8-bit or 1-bit units.
Caution: Do not change the bits of SESC0 register during timer operation. If they have to be
changed, they must be changed after setting the CE bit of the TMCC00 register to "0".
If the SESC0 register is overwritten during timer operation, the operation is not
guaranteed.
