SPRUIU1C July 2020 – February 2024 DRA821U , DRA821U-Q1
The following programming model explains how to program the module to receive an IrDA frame with parity forced to 1, baud rate = 115.2 kbps, FIFOs disabled, 2 stop-bits, and 8-bit word length:
Step | Register/Bit Field/Programming Model | Value |
---|---|---|
Disable UART mode | UART_MDR1[2-0] MODE_SELECT | 0x7 |
Grant access to the UART_DLL and UART_DLH registers | UART_LCR[7-0] | 0x80 |
Load the baud rate(115.2 Kbps) | UART_DLL[7-0] CLOCK_LSB | 0x1A |
UART_DLH[5-0] CLOCK_MSB | 0x00 | |
Set SIR mode | UART_MDR1[2-0] MODE_SELECT | 0x1 |
Disable access to the UART_DLL and UART_DLH registers | UART_LCR[7-0] | 0x00 |
Enable the UART_RHR interrupt | UART_IER_IRDA[0] RHR_IT | 1 |
