Silicon Errata Issues
1. Module: Oscillator
1.1 Operation below 2.7V
2. Module: Interrupts
 2011 Microchip Technology Inc.
Note:
The minimum device V
crystal oscillator in HS mode is 3.0V.
Work around
Use the internal oscillator or an external clock
source if operating below the 3.0V required for HS
mode.
Affected Silicon Revisions
The interrupt
addresses to the stack when vectoring to the
interrupt vector. Specifically, the interrupt vector
address 0x4 is incorrectly pushed to the stack after
the current PC, at the time the interrupt was
received, is pushed. This will cause the stack to
overflow if the user program is operating seven
calls deep when an interrupt arrives. Because the
stack is circular, the overflow causes the first stack
address to be overwritten.
Work around
Disable interrupts by clearing the GIE bit in the
INTCON register whenever the user program is
operating seven calls deep. This ensures that
interrupts will not cause the stack to overflow.
