Yes, unfortunately SW is the only way to implement master mode on the
     '64.  However, we are working on several devices that will have HW
     master mode support that will be out soon.

     Since you are here, would you mind replying to a quick customer
     survey?
     1. Do you need 10-bit address mode?
     2. Do you need fast (400KHz) mode?
     3. What is your application for IIC?

     Thanks, Brian Boles.                 bboles@microchip.com

I am currently trying to implement an IIC master mode routine
for the '64. I have a software routine which works fine, but
slowly. To speed things up I thought the hardware would help me
out, but according to the data sheet then in master mode the only
support is for start and stop bit interrupts to see if anyone else
is using the bus. Control of the bits is only through the
TRISC register, ignoring the port values, and presumably the
fast serial register.

Does anyone know if the only way to use this port is in software
for master mode ?
