UCnDIR

This bit can be rewritten only when UCnPWR bit = 0 or UCnTXE bit = UCnRXE bit = 0.
UCnPS1

1
• These bits can be rewritten only when UCnPWR bit = 0 or UCnTXE bit = UCnRXE bit
= 0.
• If "Reception with 0 parity" is selected during reception, a parity check is not performed.
Therefore, since the UCnPE bit of the UCnSTA0 register is not set, no error interrupt is
output.
• When transmission and reception are performed in the LIN format, set the UCnPS1 and
UCnPS0 bits to 00B.
UCnCL
0
1
This bit can be rewritten only when UCnPWR bit = 0 or UCnTXE bit = UCnRXE bit = 0.
UCnSL
0
1
This bit can be rewritten only when UCnPWR bit = 0 or UCnTXE bit = UCnRXE bit = 0.
Remark: For details of parity, see 15.5.9 "Parity types and operations" on page 637.
