Clarifications/Corrections to the Data
Sheet:
In the Device Data Sheet (DS30487C), the following
clarifications and corrections should be noted. Any sili-
con issues related to the PIC16F87/88 will be reported
in a separate silicon errata. Please check the Microchip
web site for any existing issues.

• INTOSC Clock Source
• INTRC Clock Source
- The Least Significant bit of the OSCTUNE
- As a result, incrementing or decrementing
- When the INTOSC clock source is started,
- The INTOSC clock frequency is stable
- This 31 kHz, internal RC oscillator source
register – TUN0 (OSCTUNE<0>) – is not
implemented.
the OSCTUNE register will not have the
expected, single-step change on the
INTOSC frequency.
the IOFS bit (OSCCON <2>) is clear, but it
becomes set in approximately 100 μs.

is a separate, fixed frequency. It is not
tunable.

PIC16F87/88 Data Sheet Errata
Change 1. Section 4.5.2
When the OSCTUNE register is modified, the INTOSC
frequency will begin shifting to the new frequency. The
INTOSC clock will stabilize within 100 μs. Code execu-
tion continues during this shift. There is no indication
that the shift has occurred.
