5.1.1.2.1. Informational requirements
The USART module must provide information about its supported communication modes . |
The USART module must provide information about the full-duplex mode. |
In full-duplex mode, both transmission and reception occur simultaneously using separate data lines for TX and RX. |
Parity checking is configured using the PCE (Parity Control Enable) and PS (Parity Selection) bits. |
The USART module includes built-in error detection for the following conditions: parity, framing and overrun errors. |
Idle line detection is supported through the IDLEIE (Idle Interrupt Enable) bit in the USART_CR1 register. |
The USART_BRR register is used to set baud rates based on the system clock frequency. |
The USART module requires a stable system clock frequency to generate the correct baud rate for communication. |
The USART module provides details about the supported data word lengths, 8-bit or 9-bit. |
