(2) UARTAn control register 1 (UAnCTL1)
(3) UARTAn control register 2 (UAnCTL2)
Note This register can be rewritten only when the UAnPWR bit = 0 or the UAnTXE bit = UAnRXE bit = 0.
Remark
For details, see 14.7 (2) UARTAn control register 1 (UAnCTL1).
For details, see 14.7 (3) UARTAn control register 2 (UAnCTL2).
However, setting any or all of the UAnPWR, UAnTXE, and UAnRXE bits to 1 at the same time is
possible.
For details of parity, see 14.6.6 Parity types and operations.
UAnPS1
UAnDIR
UAnCL
UAnSL
If “Reception with 0 parity” is selected during reception, a parity check is not performed.
Therefore, since the UAnSTR.UAnPE bit is not set, no error interrupt due to a parity
error is output.
Only the first bit of the receive data stop bits is checked, regardless of the value
of the UAnSL bit.
