UART_POST_IDLE_NUM This register is used to configure the duration between the last at_cmd
and the next data. When the duration is less than what this register indicates, it will not take the
previous data as an at_cmd char. (R/W)

UART_RX_GAP_TOUT This register is used to configure the interval between the at_cmd chars.
When the interval is greater than the value of this register, it will not take the data as continuous
at_cmd chars. The register should be configured to more than half of the baud rate. (R/W)
