12.9 Precautions on Using UART Mode
• Flags indicating the status of UART receive operation
Following flags are available that indicate the status of receive operation during UART mode.
• SIO Receive Control Register receive status bit
• SIO Receive Control Register receive-finished bit
• SIO Receive Control Register receive error sum bit
• SIO Receive Control Register overrun error bit
• SIO Receive Control Register parity error bit
• SIO Receive Control Register framing error bit
The manner in which the receive-finished bit and various error bit flags are cleared varies
depending on whether an overrun error has occurred or not, as described below.
[When no overrun error has occurred]
Said bits can be cleared by reading the lower byte from the receive buffer register or clearing the
receive enable bit to 0.
[When an overrun error has occurred]
Said bits can only be cleared by clearing the receive enable bit to 0.
