SCI0, SCI1: Serial communications interface channels 0 and 1.
ITU0–ITU3: Channels 0–3 of the 16-bit integrated-timer pulse unit.
Notes: 1. These bits are valid only in channels 0 and 1. None of these request sources can be
selected in channels 2 and 3.
2. Transfer from memory-mapped external device or external memory to external device
with DACK.
3. Transfer from external device with DACK to memory-mapped external device or
external memory.
4. Dual address mode.
