Receiving Data Using Polled Method
7. Execute an
The LIN-UART is now configured for interrupt-driven data transmission. As the LIN-
UART transmit data register is empty, an interrupt is generated immediately. When the
LIN-UART transmit interrupt is detected and there is transmit data ready to send, the asso-
ciated interrupt service rouISR performs the following:
1. If operating in MULTIPROCESSOR mode, write the LIN-UART Control 1 Register
2. Write the data byte to the LIN-UART transmit data register. The transmitter
3. Execute the
If a transmit interrupt occurs and there is no transmit data ready to send, the interrupt ser-
vice routine executes the
mit, software sets the appropriate interrupt request bit in the interrupt controller to initiate
a new transmit interrupt. Another alternative would be for software to write the data to the
transmit data register instead of invoking the ISR.
Observe the following steps to configure the LIN-UART for polled data reception:
1. Write to the LIN-UART baud rate high and low byte registers to set the appropriate
