Our customer has some problems. He wants to know that his code is correct.
Next code is for initializing interrupts of uart:TL16C752C.
He expects generating of "THR Interrupt".
Please help me how to solve his problem.
//Interrupts Disable
base_adress+0x03(LCR) write 0xBF ;for EFR access
base_adress+0x02(EFR) assert bit4 ;for IER[7:4], FCR[5:4],MCR[7:5] access
base_adress+0x03(LCR) negate bit7 ;for IER access
base_adress+0x01(IER) write 0x00
//Init. FIFO(TX trigger 8spaces, RX trigger 1characters)
base_adress+0x02(FCR) write 0x01
base_adress+0x02(FCR) write 0x07 ; Clear FIFOs
base_adress+0x02(FCR) write 0x01
//DATA :8bit, STOP bit: 1bit, Parity: no
base_adress+0x03(LCR) write 0x03
//Modem Control Setting (not use Autoflow)
base_adress+0x04(MCR) write 0x00
//Set Divisor Latches
base_adress+0x03(LCR) assert bit7 ;for DLL/DLH access
base_adress+0x00(DLL) write 0x03
base_adress+0x01(DLH) write 0x00
//Enable Interrupt (Temporary:All interrupts enabled except Sleep Mode.)
base_adress+0x03(LCR) negate bit7 ;for IER access
base_adress+0x02(IIR) read ;clear interrupt request
base_adress+0x01(IER) write 0xEF
THR Interrupt?
thanks in advance
