Module: High-Frequency Internal Oscillator (HFINTOSC) 1.1 Internal Oscillator min. VDD The High-Frequency Internal Oscillator requires a minimum voltage of 2.3V to operate. Work around None. Affected Silicon Revisions 1.2 HFINTOSC Max. VDD at -40°C For the LF devices only, the High-Frequency Internal Oscillator may stop working at -40°C when VDD is 3.6V. Work around None. Affected Silicon Revisions 2. Module: FVR 2.1 FVR Ready Bit (FVRRDY) After the FVR is stabilized, the FVR Ready bit may not be set when the temperature is -40°C and VDD = 1.8V. Work around Operate above -30°C or with VDD >2.0V. Affected Silicon Revisions 3. Module: Oscillator 3.1 OSCSTAT bits: HFIOFR and HFIOFS When HFINTOSC is selected, the HFIOFR and HFIOFS bits will become set when the oscillator becomes ready and stable. Once these bits are set, they become “stuck”, indicating that HFINTOSC is always ready and stable. If the HFINTOSC is disabled, the bits fail to be cleared. Work around None. Affected Silicon Revisions 3.2 Clock Switching When switching clock sources between INTOSC clock source and an external clock source, one corrupted instruction may be executed after the switch occurs. This issue affects Two-Speed Start-up and Fail- Safe Clock Monitor operation. Work around When switching from an external oscillator clock source, first switch to 16 MHz HFINTOSC. Once running at 16 MHz HFINTOSC, configure IRCF to run at desired internal oscillator frequency. When switching from an internal oscillator (INTOSC) to an external oscillator clock source, first switch to HFINTOSC High-Power mode (8 MHz or 16 MHz). Once running from HFINTOSC, switch to the external oscillator clock source. Affected Silicon Revisions Note: This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current. Only the issues indicated by the shaded column in the following tables apply to the current silicon revision (A6). A2 A3 A4 A6 X A2 A3 A4 A6 X A2 A3 A4 A6 X A2 A3 A4 A6 XX X A2 A3 A4 A6 XX X |
