Bits 7 to 0: Address Pointer (ADDP). This pointer is used to switch between pointing to the primary registers, the
secondary registers, individual registers, and BERT registers. See Table 6-14 for bank selection. The register
space contains control for Channels 1 to 8 from address 00 hex to 1F hex and a duplicate set of registers for
control of Channels 9 to 16 from address 20 hex to 3F hex. The ADDP at address 1F hex select the banks for the
set of registers for LIUs 1–8. The ADDP register at address 3F select the banks for the set of registers for LIUs 9–
16.
