Description
Receiving is in progress or has ended normally*¹
(initial value)
Clearing conditions:
• Power-on reset or standby mode
• When 0 is written to ORER after reading ORER =
1
A receive overrun error occurred
Setting condition: When the next serial reception is
completed while RDRF = 1*²
Receiving is in progress or has ended normally*³
(initial value)
Clearing conditions:
• Power-on reset or standby mode
• When 0 is written to FER after reading FER = 1
A receive framing error occurred*⁴
Setting condition: When at the end of an SCI receive
operation the final stop bit of the receive data is
checked and its value*⁴ is 0
Receiving is in progress or has ended normally*⁵
(initial value)
Clearing conditions:
• Power-on reset or standby mode
• When 0 is written to PER after reading PER = 1
A receive parity error occurred*⁶
Setting condition: PER is set to 1 if the number of 1s in
receive data, including the parity bit, does not match
the even or odd parity setting of the parity mode bit
(O/E) in the serial mode register (SMR)
