Bit 3—Stop Bit Length (STOP): Selects 1 or 2 bits as the stop bit length in asynchronous mode.
The STOP bit setting is only valid in asynchronous mode. If synchronous mode is set, the STOP
bit setting is invalid since stop bits are not added.
Bit 3: STOP
Description
0
1 stop bit^*1
(Initial value)
1
2 stop bits^*2
Notes: 1. In transmission, a single 1-bit (stop bit) is added to the end of a transmit character
before it is sent.
2. In transmission, two 1-bits (stop bits) are added to the end of a transmit character
before it is sent.
In reception, only the first stop bit is checked, regardless of the STOP bit setting. If the second
stop bit is 1, it is treated as a stop bit; if it is 0, it is treated as the start bit of the next transmit
character.
Bit 2—Multiprocessor Mode (MP): Selects a multiprocessor format. When a multiprocessor
format is selected, the PE bit and O/E bit parity settings are invalid. The MP bit setting is only
valid in asynchronous mode; it is invalid in synchronous mode.
For details of the multiprocessor communication function including notes on use, see section
15.3.3, Multiprocessor Communication Function.
Bit 2: MP

Bits 1 and 0—Clock Select 1 and 0 (CKS1, CKS0): These bits select the clock source for the on-
chip baud rate generator. The clock source can be selected from Pck, Pck/4, Pck/16, and Pck/64,
according to the setting of bits CKS1 and CKS0.
