These new devices are: • PIC16C83 • PIC16CR83 • PIC16C84A • PIC16CR84 Some of the issues that may be encountered are: 1. The polarity of the PWRTE configuration bit has been reversed. Ensure that the programmer has this bit correctly set before programming. 2. The PIC16C84A and PIC16CR84 have larger RAM sizes. Ensure that this does not cause an issue with your program. 3. The MCLR pin now has an on-chip filter. The input signal on the MCLR pin will require a longer low pulse to generate an interrupt. 4. Many electrical specifications have been improved. Compare the electrical specifications of the two devices to ensure that this will not cause a compatibility issue. |
