Section 15 Serial Communication Interface (SCI, IrDA)
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.

Notes: 1. In transmission, a single 1 bit (stop bit) is added to the end of a transmit character
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 multiprocessor format. When 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, see section 15.3.3, Multiprocessor
Communication Function.

Bits 1 and 0—Clock Select 1 and 0 (CKS1, CKS0): These bits select the clock source for the
baud rate generator. The clock source can be selected from , /4, /16, and /64, according to the
setting of bits CKS1 and CKS0.
For the relation between the clock source, the bit rate register setting, and the baud rate, see
section 15.2.8, Bit Rate Register (BRR).
