Address 05h corresponds to channel 0, address 06h corresponds to channel 1, address 07h corresponds to
channel 2, address 08h corresponds to channel 3, address 09h corresponds to channel 4, address 0Ah
corresponds to channel 5, address 0Bh corresponds to channel 6, and address 0Ch corresponds to channel 7.
