RXD
Configures the P90 pin as TXD0 and the P91
pin as RXD0
Enables INTRX0 and sets its interrupt level to 5.
Enables INTTX0 and sets its interrupt level to 4.
Selects 9-bit UART mode and selects fsys/2 as
a serial clock.
Loads the select code for slave 1.
Clears the interrupt request.
Clears the TB0 bit to 0.
Loads the transmit data.
Configures the P90 pin as TXD (open-drain
output) and the P91 pin as RXD.
Enables INTTX0 and INTRX0.
Selects 9-bit UART mode, selects fsys/2 as the
serial clock and and sets the WU bit to 1.
Clears the interrupt request.
Clears the WU bit to 0.
