Silicon Errata Issues
1. Module: COG
1.1 Full-Bridge Mode
When operating with a non-zero duty cycle in
Full-Bridge mode and the direction is switched
from forward to reverse, then it is possible for both
the high-side and low-side drivers to be conducting
current simultaneously, thereby causing
shoot-through current.
Work around
Prior to switching to reverse, set the duty cycle to
zero for a minimum of one period.
Affected Silicon Revisions
1.2 Input Blanking May Not Release
When level mode input sensitivity is selected, input
blanking is not zero, and a rising event occurs
simultaneously with a falling event, then the
blanking circuit that inhibits falling events will
remain in the blanking state and the COG output
will remain in the active state until a shutdown
event or COG module Reset.
Work around
Use edge sensitivity or set blanking times to zero.
Affected Silicon Revisions
2. Module: Power-down Mode
2.1 Sleep Current
On the PIC16(L)F1704 device the Sleep currents
may increase at temperatures below -20°C.
Work around
Enable the global weak pull-up bit (WPUEN) in
the OPTION register (OPTION_REG) and
disable the weak pull-ups that are not needed in
the WPUA and WPUC registers.
Affected Silicon Revisions
3. Module: Comparator
3.1 Low-Power Mode
Unexpected performance may result when
operating the comparator in Low-Power,
Low-Speed mode (CxSP = 0).
Work around
Use the comparator in High-Speed, High-Power
mode (CxSP = 1).
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).
