16-bit 2-Phase Encoder Input Up/Down Counter/General Purpose Timer (TMENC10)

Signal edge selection register 10 (SESA10)
The SESA10 register specifies the valid edge of external interrupt requests from external pins
(TICC10, TICC11, TCLR1).
The valid edge (rising edge, falling edge, or both edges) can be specified independently for each
pin.
This register can be read or written in 8-bit or 1-bit units.
Reset input clears this register to 00H.
Cautions: 1. Changing the values of the SESA10 register bits during TMENC10 operation
(TM1CE bit = 1) is prohibited.
2. Be sure to set (1) the TM1CE bit of timer control register 1 (TMC10) even when
TMENC10 is not used and the TICC10 and TICC11 pins are used as external
interrupts INTCC10 and INTCC11 respectively.
3. Before setting the trigger mode of the TICC10, TICC11, and TCLR1n pins, set the
PM10 and PMC10 registers. If the PM10 and PMC10 registers are set after the
SESA10 register has been set, an illegal interrupt, incorrect counting, and
incorrect clearing may occur, depending on the timing of setting the PM10 and
PMC10 registers.

The set values of the TESUD1 and TESUD0 bits are only valid in UDC mode A and
UDC mode B.
•
If mode 4 is specified as the operation mode of TMENC10 (specified with PRM102 to
PRM100 bits of PRM10 register), the valid edge specifications for the TIUD1 and
TCUD1 pins (TESUD1 and TESUD0 bits) are not valid.
