Framing Error /w USART

I have an application where I need to collect data after a framing error has occurred. What I've found so far is I have to be reading the port via HSERIN to sense a framing error. Is there any way to sense a framing error without needing to read RCREG or HSERIN?

I'm assuming not but I thought I would ask to save some time.

Hi Ben,

The only problem is that if you don't read RCREG, the USART will stop after receiving 2 bytes. Then it'll never see a framing error.

A very simple interrupt routine could solve that though.
Just a quick example...

Code:

---

CREN  VAR RCSTA.4
FERR  VAR RCSTA.2
OERR  VAR RCSTA.1
RCIE  VAR PIE1.5
Dummy  VAR BYTE

ON INTERRUPT GOTO USART_Handler
RCIE = 1            ; Enable USART RX INTs

Main:
    IF FERR THEN
        FERR = 0
        TOGGLE LED  ; Do something here
    ENDIF
GOTO Main

DISABLE
USART_Handler:
    IF OERR then    ; Clear Overrun Errors
        CREN = 0
        CREN = 1
    ENDIF
    Dummy = RCREG    ; Empty USART Buffer and Clear RCIF
RESUME
ENABLE

HTH,

Another case of I want what I can't have. ;) Just trying to keep the code tight. I actually have a similar routine I guess thats the method I'm sticking with. Thanks!
