1 stop bit:
In transmission, a single 1 bit (stop bit) is added to the
end of a transmit character before it is sent.

2 stop bits: In transmission, two 1 bits (stop bits) are added to the
end of a transmit character before it is sent.

Notes: 1. When even parity is set, parity bit addition is performed in transmission
so that the total number of 1 bits in the transmit character plus the parity
bit is even.
In reception, a check is performed to see if the total number of 1 bits in
the receive character plus the parity bit is even.
2. When odd parity is set, parity bit addition is performed in transmission
so that the total number of 1 bits in the transmit character plus the parity
bit is odd.
In reception, a check is performed to see if the total number of 1 bits in
the receive character plus the parity bit is odd.
Note:
*
When the PE bit is set to 1, the parity (even or odd) specified by the O/
E
bit is
added to transmit data before transmission. In reception, the parity bit is checked
for the parity (even or odd) specified by the O/
E
bit.

Note:
*
When 7-bit data is selected, the MSB (bit 7) of TDR is not transmitted, and
it is not possible to choose between LSB-first or MSB-first transfer.
