mbed_official | 205:c41fc65bcfb4 | 35 | __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process. |
mbed_official | 205:c41fc65bcfb4 | 36 | (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA() |

mbed_official | 205:c41fc65bcfb4 | 140 | in the data register is transmitted but is changed by the parity bit. |
mbed_official | 205:c41fc65bcfb4 | 141 | Depending on the frame length defined by the M bit (8-bits or 9-bits) |
