User manual
UART0 is available on all LPC122x parts.
Clocks and power to the UART0 block are controlled by:
Remark: The UART0 pins must be configured in the corresponding IOCON registers
before the UART0 clocks are enabled.
The UART0_PCLK can be disabled in the UART0CLKDIV register (see
the UART block can be disabled through the System AHB clock control register bit 12
