5. 8-Bit Control Register Summary
Any register not listed here is reserved and must not be written. Shaded registers are read only. All registers are
assigned a default value during initialization and following a system reset. Only registers 0, 2, 3, and 14 are
available until a PLL lock is established or during a clock failure.
(Ordered alphabetically by mnemonic.)
3
Any register not listed is reserved and must not be written. Default hex value is loaded to register following any RESET. Only registers ID, MSTREN, MSTRSTAT, and IRQ0 are valid while the
PLL is not locked (MSTRSTAT[PLOCK]).
Reserved bit values are indeterminate.
Register address is in decimal.
Read only.
Protected bits.
Per-channel bit(s).
