Description
Reserved
This bit is always read as 0. The write value should
always be 0.
TMU_SUNI Interrupt Request
Indicates whether the TMU_SUNI (TMU) interrupt request
is generated.
0: TMU_SUNI interrupt request is not generated
1: TMU_SUNI interrupt request is generated
IRQn Interrupt Request
Indicates whether there is interrupt request input to the
IRQn pin. When edge-detection mode is set for IRQn, an
interrupt request is cleared by writing 0 to the IRQnR bit
after reading IRQnR = 1.
When level-detection mode is set for IRQn, these bits
indicate whether an interrupt request is input. The
interrupt request is set/cleared by only 1/0 input to the
IRQn pin.
IRQnR
0: No interrupt request input to IRQn pin
1: Interrupt request input to IRQn pin
[Legend] n = 0 to 5
