UART ID register
ID | This register is used to configure the uart_id. |
HIGH_SPEED | This bit used to select synchronize mode. 1: Registers are auto synchronized into UART Core clock and UART core should be keep the same with APB clock. 0: After configure registers, software needs to write 1 to UART_REG_UPDATE to synchronize registers. |
REG_UPDATE | Software write 1 would synchronize registers into UART Core clock domain and would be cleared by hardware after synchronization is done. |
