Serial I/O1
Asynchronous serial I/O (UART) mode
Serial I/O1 can be used as an asynchronous (UART) serial I/O. A
dedicated timer (baud rate generator) is also provided for baud rate
generation when serial I/O1 is in operation.
Eight serial data transfer formats can be selected, and the transfer
formats to be used by a transmitter and a receiver must be identi-
cal.
Each of the transmit and receive shift registers has a buffer register
(the same address on memory). Since the shift register cannot be
written to or read from directly, transmit data is written to the trans-
mit buffer, and receive data is read from the respective buffer regis-
ters. These buffer registers can also hold the next data to be trans-
mitted and receive 2-byte receive data in succession.
By selecting “1” for continuous transmit valid bit (bit 2 of SIO1CON),
continuous transmission of the same data is made possible.
This can be used as a simplified PWM.

1 :
Error flag detection occurs at the same time that the RBF flag becomes “1” (at 1st stop bit, during reception).
2 :
The transmit interrupt (TI) can be selected to occur when either the TBE or TSC flag becomes “1”, depending on the setting of the transmit
interrupt source selection bit (TIC) of the serial I/O1 control register.
3 :
The receive interrupt (RI) is set when the RBF flag becomes “1”.
4 :
After data is written to the transmit buffer when TSC = 1, 0.5 to 1.5 cycles of the data shift cycle is necessary until changing to TSC = 0.
