PSG.LlB Functions
void slta-init(slta-format, slta-baud, slta-intfc);
This function initializes the UART.
It sets up the frame format, the serial
interface bit rate, and the modem handshake lines. The frame format
parameters are listed in PSG . H and may be set to:
format-6Nl

The slta-baud parametermaybesetto baud~300,baud~600,baud_1200,
baud~2400,baud~4800,baud_9600,baud_1440019200,baud~38400,
baud-5 7 6 0 0, or baud-l 15 2 0 0.
The EIA-232 interface parameter may be set to
intf c_3wire, or int f c-8wire.
Configuration switch inputs are ignored-all
configuration information is taken from the parameters supplied to
s 1 ta-ini t ( ) . This function should be called once in the reset clause of the
application program.
Example:
when (reset) {
slta-init(format_8Nl, baud-38400, intfc-3wire);
