Description
IRQ0 Sense Control B
IRQ0 Sense Control A
00: Interrupt request is generated at IRQ0 input level low
01: Interrupt request is generated at falling edge of IRQ0
10: Interrupt request is generated at rising edge of IRQ0
11: Interrupt request is generated at both falling and rising
Description

input
edges of IRQ0 input
When the interrupt source selected by the ISCR
registers occurs
Cleared by reading IRQnF flag when IRQnF = 1, then
writing 0 to IRQnF flag
When interrupt exception handling is executed while
low-level detection is set and IRQn (n = 0 to 7) input
is high
When IRQn interrupt exception handling is executed
while detection of falling edge, rising edge, or both
edges is set
When the DTC is activated by an IRQn interrupt, and
the DISEL bit in MRB of the DTC with the transfer
counter other than 0 is cleared to 0
