PIC12CE67X Clarifications/Corrections to the Data Sheet: In the Device Data Sheet (DS30561B), the following clarifications and corrections should be noted. 1. Module: Register Summary (OSCCAL) In Section 4.0, corrections for the Special Function Register Summary, Table 4-1, are shown.
PAGE 5
PIC12CE67X 2. Module: OSCCAL Register Correction for the “OSCCAL” Register, Section 4.2.2.7, is shown. 4.2.2.7 OSCCAL REGISTER The Oscillator Calibration (OSCCAL) Register is used to calibrate the internal 4 MHz oscillator. It contains six bits for calibration. Increasing the value increases the frequency.

PIC12CE67X 4. Module: OSCCAL (Oscillator) Corrections for the Internal 4 MHz RC Oscillator, Section 9.2.5, are shown. 9.2.5 INTERNAL 4 MHz RC OSCILLATOR OSCCAL, when written to with the calibration value, will “trim” the internal oscillator to remove process variation from the oscillator frequency. Only bits<7:2> of OSCCAL are implemented, and bits<1:0> should be written as 0 for compatibility with future devices. The oscillator calibration location is not code protected. 5.

Note the following details of the code protection feature on PICmicro® MCUs. • • • • • • The PICmicro family meets the specifications contained in the Microchip Data Sheet. Microchip believes that its family of PICmicro microcontrollers is one of the most secure products of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature.
