PIC16F505 Rev. A Silicon/Data Sheet Errata
The PIC16F505 parts you have received conform functionally to the Device Data Sheet (DS41236D), except for the anomalies described below. Microchip intends to address all issues listed here in future revisions of the PIC16F505 silicon or development tools software. Where noted, issues apply to listed revision only.
2. Module: Invalid FSR Power-up Initialization on PIC16F505 ICD Devices
When using the ICD to debug software with the PIC16F505, bits 5 and 6 in the FSR register must be cleared to `0'. The power-up defaults are 1's which causes the device to attempt to access bank 3. This bank is not available on the PIC16F505 devices so the results are invalid. The power-up defaults are correct on the non-ICD version of the PIC16F505. Work around: Add the following two lines of code early in your initialization. BCF BCF FSR,5 FSR,6
