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