6.3.4 UART1 and UART2 Register Map
The LPC IO Base addresses BASE1 for UART1 and BASE2 for UART2 are set up during Super IO
configuration. See
Super IO Configuration Registers on page 169 .
6.3.4.1 UART Register Overview
Table 6-26 on page 176 shows the registers and their addresses as offsets of a base address for
one of the two UARTs.
An Interrupt is activated by enabling this device (offset 0x30), setting this register to a non-
zero value and setting any combination of bits 0-4 in the corresponding UART IER and the
occurrence of the corresponding UART event (i.e. Modem Status Change, Receiver Line Error
Condition, Transmit Data Request, Receiver Data Available or Receiver Time Out) and setting
the OUT2 bit in the MCR.
