PIC16C55X(A) Errata Sheet for the PIC16C55X(A) Rev. A Data Sheet The PIC16C55X(A) (Rev. A) parts you received conform functionally to the PIC16C55X(A) preliminary data sheet (DS40143B), except for the anomalies described below. * Module: Reset * Description: Power-up Timer stays enabled regardless of the PWRTE setting (bit 3 of configuration word). * Workaround: Clear reserved bit 6 of the configuration word to 0 during programming. In the MPLABTM programmer window, this bit is listed as Brown Out Detect. This will allow PWRTE to function correctly. FIGURE 7-1: CP1 CP01 Clarifications/Corrections to the Data Sheet: The PIC16C55X(A) Data Sheet (DS40143B), Table 72, calls out the incorrect crystals for the use with our PICmicrosTM. The table updated below lists the standard parallel cut versions.

These values are for design guidance only. Rs may be required in HS mode as well as XT mode to avoid overdriving crystals with low drive level specification. Since each crystal has its own characteristics, the user should consult the crystal manufacturer for appropriate values of external components.
