CHAPTER 9 TIMER/COUNTER FUNCTION (REAL-TIME PULSE UNIT)

312

User’s Manual U14492EJ3V0UD

(5) Signal edge selection registers 10, 11 (SESA10, SESA11)

The SESA1n register is used to specify the valid edge of external interrupt requests from external pins

(INTP100, INTP101, INTP110, INTP111, TIUD10, TIUD11, TCUD10, TCUD11, TCLR10, TCLR11). The

correspondences between each register and the external interrupt requests it controls are as follows.

•

SESA10: TIUD10, TCUD10, TCLR10, INTP100, INTP101

•

SESA11: TIUD11, TCUD11, TCLR11, INTP110, INTP111

The valid edge (rising edge, falling edge, or both edges) can be specified independently for each pin.

SESA1n can be read/written in 8-bit or 1-bit units.

Cautions 1. Changing the values of the SESA1n register bits during TM1n operation (TM1CEn bit =

1) is prohibited.

2. Be sure to set (to 1) the TM1CEn bit of timer control registers 10, 11 (TMC10, TMC11)

even when timer 1 is not used and the TCUD10/INTP100, TCLR10/INTP101,

TCUD11/INTP110, and TCLR11/INTP111 pins are used as INTP100, INTP101, INTP110,

and INTP111.

Setting prohibited

Both rising and falling edges

7, 6

TESUDn1,

TESUDn0

Cautions 1. The set values of the TESUDn1 and TESUDn0 bits are only valid

in UDC mode A and UDC mode B.

2. If mode 4 is specified as the operation mode of TM1n (specified

with PRM12 to PRM10 bits of PRM1n register), the valid edge

specifications for pins TIUD1n and TCUD1n (bits TESUDn1 and

TESUDn0) are not valid.
