0 0 0 0 : Falling edge of INT0 pin
0 0 0 1 : Software trigger
0 0 1 0 : Timer A0
0 0 1 1 : Timer A1
0 1 0 0 : Timer A2
0 1 0 1 : Timer A3
0 1 1 0 : Timer A4
0 1 1 1 : Timer B0
1 0 0 0 : Timer B1
1 0 0 1 : USB0
1 0 1 0 : UART0 transmit
1 0 1 1 : UART0 receive
1 1 0 0 : UART2 transmit
1 1 0 1 : UART2 receive
1 1 1 0 : A-D conversion
1 1 1 1 : UART1 transmit
If software trigger is selected, a
DMA request is generated by
setting this bit to "1" (When read,
the value of this bit is always "0")
