UART Pin Description
APB
Peripheral
Bridge
The UART pins are multiplexed with PIO lines. The programmer must first configure the corre-
sponding PIO Controller to enable I/O line operations of the UART.
Table 32-2.
The UART clock is controllable through the Power Management Controller. In this case, the pro-
grammer must first configure the PMC to enable the UART clock. Usually, the peripheral
identifier used for this purpose is 1.
