PIC12C67X 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.
PIC12C67X 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.

PIC12C67X 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.
PIC12C67X 6. Module: DC Characteristics Corrections for the DC Characteristics, Sections 12.3 and 12.4 are shown. 12.3 DC CHARACTERISTICS: DC CHARACTERISTICS Param No.
