5 Operating Control and Status
Overall T8110L operational control and status is configured via registers occupying 0x00100—0x001FC in the
address space.
5.1 Control Registers
General control functions are soft reset, reset configuration, overall master output enables, and data memory con-
figuration. Clocking-specific general control functions are clock register access configuration, phase alignment,
clock fallback, and clock watchdog configuration.
Table 15. Control Register Map
5.1.1 Reset Registers
The soft reset and reset select registers control soft reset functions and reset signal masking. Writes to the soft
reset register trigger the corresponding action, and the set bit(s) are automatically cleared.
