changing inputs and access to ccp pins for input

[p.nyffeler]

For my project I need inputs with TTL inputs (logic 0: <=.8V ,logic 1:>=2.4V).
I guess this can be easily done by changing the voltage divider at the inputs.
Does anybody know which resistors are assigned to the input pins?

Further I need pin RC2 (CCP1) and RC1(CCP2) or RB3 (alternate pin for CCP2) as input for pulse width measurement.
I expect this will be more difficult since RC1 and RC2 are used for the transistor outputs and I don't know whether RB3 is internally used nor how to access it.
Is there any chance to me to modify the MIAC that it can be used for pulse width measurement?

Of course a schematic diagram of the entire MIAC could answer all this questions. Is it available?

The pins you need for pulse width measurement are already allocated on MIAC, and the input pins work at different voltages (<3V = logic low, >8V = logic high).

I suggest you use E-blocks or an ECIO module instead of the MIAC.
