APPENDIX C
REGISTERS
This appendix provides reference information about the device registers. Table C-1 lists the mod-
ules and major components of the device with their related configuration and status registers. Ta-
ble C-2 lists the registers, arranged alphabetically by mnemonic, along with their names,
addresses, and reset values. Following the tables, individual descriptions of the registers are ar-
ranged alphabetically by mnemonic.
