3.3.4.2 Default Configuration
The default software configuration of UART1 is console mode. Boot traces are
sent on this interface as shown on Section 5.4.2 Confirm Module Power-Up
Operation (UART1) on page 32.
The serial link settings are as follows:
• Baud rate: 115200
• Data: 8 bits
•Parity: None
• Stop : 1 bit
•Flow control: None
3.3.5 UART2 Interface
3.3.5.1 Interface Description
Important:
• See the Section 3.3.2 General Notes on UART Connections on
page 10 for usage of UART2.
• If not used, the UART2 signals should be connected to test
points.
Table 3-7 lists the VZM20Q pins related to the UART2 interface.
