I'm working on teaching myself how to program the PIC family of microcontrollers and have run across a simple question that the datasheet is not answering for me.
On the 16F84A, RA4/TOCK1 is not going high when I send it the signal (no problem with RA0-RA3). Given that this is a TTL/ST multiplexed pin, do I need to setup another register (OPTION_REG?) so that this can be used as a true output (TRISA is already set as 00h)? Or is this an input only pin?
Thanks,
Chuck
