Notes: 1. Lower 16 bits of the address
2. Only 0 can be written to bits 7 to 5, to clear these flags.
Each pair of registers for channel 0 (channel 2) and channel 1 (channel 3) is a 16-bit register with
the upper 8 bits for channel 0 (channel 2) and the lower 8 bits for channel 1 (channel 3), so they
can be accessed together by word transfer instruction.
