NOTES:

IOC2

To select 1 (the TRDGRCi register is used as a buffer register of the TRDGRAi register) for this bit by the BFCi bit in

the TRDMR register, set the IOC2 bit in the TRDIORCi register to the same value as the IOA2 bit in the TRDIORAi

TRDGRD mode select bit(2)

Set to 0 (output compare) in the output compare

function.
