18F4620 - Trying to modify CONFIG 3H

[rswain]

I need the CCP2MX bit in CONFIG 3H turned OFF, allowing CCP2 to be assigned to port B. There's got to be a way to set it and forget it in the INCLUDE file. I'm sure this is simple, but all the obvious ways I've tried still haven't worked.

Any help would be appreciated!

Hi Robert,
Try this line this way:Red added:
__CONFIG _CONFIG3H, _PBADEN_OFF_3H <font color = red>& _CCP2MX_PORTBE_3H</font color>

Look in MPASM SUITE for the P18F4620.inc file, there you will find all the configs for this chip

;----- CONFIG3H Options --------------------------------------------------
_MCLRE_OFF_3H        EQU  H'7F'    ; Disabled
_MCLRE_ON_3H         EQU  H'FF'    ; Enabled

_LPT1OSC_OFF_3H      EQU  H'FB'    ; Disabled
_LPT1OSC_ON_3H       EQU  H'FF'    ; Enabled

_PBADEN_OFF_3H       EQU  H'FD'    ; PORTB<4:0> digital on Reset
_PBADEN_ON_3H        EQU  H'FF'    ; PORTB<4:0> analog on Reset

_CCP2MX_PORTBE_3H    EQU  H'FE'    ; Multiplexed with RB3
_CCP2MX_PORTC_3H     EQU  H'FF'    ; Multiplexed with RC1
;----- CONFIG5L Options --------------------------------------------------
_CP0_ON_5L           EQU  H'FE'    ; Enabled
_CP0_OFF_5L          EQU  H'FF'    ; Disabled

_CP1_ON_5L           EQU  H'FD'    ; Enabled
_CP1_OFF_5L          EQU  H'FF'    ; Disabled

_CP2_ON_5L           EQU  H'FB'    ; Enabled
<font color=red>_CP2_OFF_5L          EQU  H'FF'    ; Disabled</font color>

_CP3_ON_5L           EQU  H'F7'    ; Enabled
_CP3_OFF_5L          EQU  H'FF'    ; Disabled
