STOP Bit (Stop Bit Length)
Selects the stop bit length in transmission.
In reception, only the first stop bit is checked regardless of this bit setting. If the second stop bit is 0, it is treated as the
start bit of the next transmit frame.
PM Bit (Parity Mode)
Selects the parity mode (even or odd) for transmission and reception.
The setting of the PM bit is invalid in multi-processor mode.
PE Bit (Parity Enable)
When this bit is set to 1, the parity bit is added to transmit data, and the parity bit is checked in reception.
Irrespective of the setting of the PE bit, the parity bit is not added or checked in multi-processor format.
CHR Bit (Character Length)
Selects the data length for transmission and reception.
Selects in combination with the CHR1 bit in SCMR.
In other than asynchronous mode, a fixed data length of 8 bits is used.
