CHAPTER 10 SERIAL INTERFACE FUNCTION
• 0 parity
During transmission, the parity bit is cleared (0) regardless of the transmit data.
During reception, no parity error is generated because no parity bit is checked.
• No parity
No parity bit is added to transmit data.
During reception, the receive data is considered to have no parity bit. No parity
error is generated because there is no parity bit.
Specifies character length of 1 frame of transmit/receive data.
0: 7 bits
1: 8 bits
Caution To overwrite the CL bit, first clear (0) the TXE0 and RXE0 bits.
Specifies stop bit length of transmit data.
0: 1 bit
1: 2 bits
Cautions 1. To overwrite the SL bit, first clear (0) the TXE0 bit.
2. Since reception is always done with a stop bit length of 1, the
SL bit setting does not affect receive operations.
Enables/disables generation of reception completion interrupt requests when an
error occurs.
0: Generate a reception error interrupt request (INTSER0) as an interrupt when
an error occurs.
In this case, no reception completion interrupt request (INTSR0) is
generated.
1: Generate a reception completion interrupt request (INTSR0) as an interrupt
when an error occurs.
In this case, no reception error interrupt request (INTSER0) is generated.
Caution To overwrite the ISRM bit, first clear (0) the RXE0 bit.
