UARTPeriphID0 register

The UARTPeriphID0 register is hard coded and the fields in the register determine the reset

value.

Table 131 lists the register bit assignments.

UARTPeriphID1 register

The UARTPeriphID1 register is hard coded and the fields in the register determine the reset

value.

Table 132 lists the register bit assignments.

UARTPeriphID2 register

The UARTPeriphID2 register is hard coded and the fields in the register determine the reset

value.

Table 133 lists the register bit assignments.
