I GOT INFO FROM PHILIPS THAT I CAN PRODUCE 2457600Hz WITH PCA HOGH SPEED OUTPUT. I DID EVERYTHING WHAT PHILIPS SUGGESTED. I DIDN'T HAVE SUCCESS.
I CAN'T PRODUCE 2457600Hz WITH PCA HS OUTPUT...
MY CODE IS:
;---------------------------------------------------------------------------
; init high speed out without interrupts
;---------------------------------------------------------------------------
;
;cpu has clock 9 830 400 Hz
;will generate 2 457 600 Hz

IN_FREQ_G:
MOV CMOD,#02H ;input to PCA timer = 1/2 fosc
MOV CH,#00
MOV CL,#00
MOV CCAPM3,#4CH ;hso mode without interrupt enabled on
module three
MOV CCAP3L,#01H ;fg = 2457600Hz
MOV CCAP3H,#00H
SETB CR ;TURN ON PCA
RET


I GOT ONLY 37.31Hz,

I TRIED NEXT ROUTINE TOO:

IN_FREQ_G: MOV CMOD,#02H ;input to PCA timer = 1/2 fosc
MOV CH,#00
MOV CL,#01
MOV CCAPM3,#4CH ;hso mode without interrupt enabled on
module three
; MOV CCAP3L,#01H ;fg = 2457600Hz
; MOV CCAP3H,#00H
SETB CR ;TURN ON PCA
RET

I GOT SAME...
WHAT'S WRONG, WHAT I HAVE TO DO TO PRODUCE RIGHT FREQUENCY?
THANKS...
