tmr1 and tmr1 ext osc

Post by brandonb »

at least with 16f1939 when enable tmr1 it cuts out useage of c0,c1 pins... the problem is when select instruction clock as source it should clear bit 3 in t1con register... after enable tmr1 put this line of code afterwards to regain control of c0,c1 pins

Code: Select all

t1con&=~(1<<3);
