Notes: 1. Indicates the lower 20 bits of the address in advanced mode.
2. Only 0 can be written to bits 7 to 5, to clear these flags.
Each pair of registers for channel 0 and channel 1 comprises a 16-bit register with the channel 0
register as the upper 8 bits and the channel 1 register as the lower 8 bits, so they can be accessed
together by word access.
Similarly, each pair of registers for channel 2 and channel 3 comprises a 16-bit register with the
channel 2 register as the upper 8 bits and the channel 3 register as the lower 8 bits, so they can be
accessed together by word access.
