SCISR register description (continued)
SCICR1 register description
Framing Error
Parity Error
Receive data bit 8
Transmit data bit 8
Disabled for low power consumption
Word length
This bit is set by hardware when a desynchronization, excessive noise or a break
character is detected. It is cleared by a software sequence (an access to the SCISR
register followed by a read to the SCIDR register).
0: No framing error is detected
1: Framing error or break character is detected
Note: This bit does not generate interrupt as it appears at the same time as the
RDRF bit which itself generates an interrupt. If the word currently being transferred
causes both Frame Error and Overrun error, it is transferred and only the OR bit will
be set.
This bit is set by hardware when a parity error occurs in receiver mode. It is cleared
by a software sequence (a read to the status register followed by an access to the
SCIDR data register). An interrupt is generated if PIE = 1 in the SCICR1 register.
0: No parity error
1: Parity error
R/W
This bit is used to store the 9th bit of the received word when M = 1.
This bit is used to store the 9th bit of the transmitted word when M = 1.
When this bit is set the SCI prescalers and outputs are stopped and the end of the
current byte transfer in order to reduce power consumption.This bit is set and
cleared by software.
0: SCI enabled
1: SCI prescaler and outputs disabled
This bit determines the word length. It is set or cleared by software.
0: 1 Start bit, 8 data bits, 1 Stop bit
1: 1 Start bit, 9 data bits, 1 Stop bit
Note: The M bit must not be modified during a data transfer (both transmission and
reception).
