1) I'd like to design a small binary watch and I would
use a 4mhz internal oscillator together with a 32768hz
xtal for clock timing (also in SLEEP mode)
The problem is that most pics I have share RB6-RB7 (ICSP pins)
with the T1OSO T1OSI pins.
Are there any 16/18 pin pics in SOIC package that have separate pins
for ICSP and T1OSO T1OSI ?
2) Is it an option to use a 32768hz xtal for system clock ?
I guess instruction time is relatively long in this case?
for a pic that means only 8192 instructions / sec.
