15. Serial Communication Interface (SCI)
15.1.3
Table 15.1 shows the SCI pin configuration.

Transmit data pin
Note: They are made to function as serial pins by performing SCI operation settings with the TE,
15.1.4
The SCI has the internal registers shown in table 15.2. These registers are used to specify
asynchronous mode or synchronous mode, the data format, and the bit rate, and to perform
transmitter/receiver control.
With the exception of the serial port register, the SCI registers are initialized in standby mode and
in the module standby state as well as after a power-on reset or manual reset. When recovering
from standby mode or the module standby state, the registers must be set again.
