2.15 UART Interface
The C6657 has two UART ports- UART0 and UART1. UART1 is directly connected to 80-pin expansion header
while a serial port is provided for UART communication using an I2C-UART bridge for UART0. This serial port
can be accessed either through USB connector (USB1) or through 3-pin (Tx, Rx and Gnd) serial port header
(COM1). The selection can be made through UART Route Select shunt-post COM_SEL1 as follows:
UART over mini-USB Connector - Shunts installed over COM_SEL1.3- COM_SEL1.1 and COM_SEL1.4
- COM_SEL1.2
(Default)
UART over 3-Pin Header (COM1) - Shunts installed over COM_SEL1.3- COM_SEL1.5 and
COM_SEL1.4 - COM_SEL1.6
