Title: HC68HC908JB8 PORTA
Post by: Gizmo on October 12, 2004, 01:28:33 am

hi

i have problems to run a blink program on the port A.
there are no signals. what i did:

- configured the keyboard interrupt enable register to KBIE = 0x00
- configured the port option register to POCR = POCR | 0x01; // internal pullups
- configured the data direction register port a to DDRA = 0xFF; // all outputs

but i don\'t get any signals on a port A pins
