15. Asynchronous Serial interface (UART)
15.1 Configuration
TXD and RXD pin. TXD and RXD pin are also used as the general port. For TXD pin, the corresponding general
port should be set output mode (Set its output control register to "1" after its output port latch to "1"). For RXD pin,
should be set input mode.
The TMP88FH41UG has a asynchronous serial interface (UART) . It can connect the peripheral circuits through
This UART and SIO can not use simultaneously because their input/output ports are common.
