3.3.3.2 Default Configuration
The default software configuration of UART0 is AT Commands mode.
The serial link settings are as follows:
• Baud rate: 921600
• Data: 8 bits
•Parity: None
• Stop : 1 bit
• Flow control: Hardware (RTS/CTS)
3.3.4 UART1 Interface
3.3.4.1 Interface Description
Important:
• See the Section 3.3.2 General Notes on UART Connections on
page 10 for usage of UART1.
• If not used, the UART1 signals should be connected to test
points.
Table 3-6 lists the VZM20Q pins related to the UART1 interface.
