4. Module: External Oscillator
4.1 Minimum Operating Voltage for HS Mode
The minimum device V
DD when using the external
crystal oscillator in HS mode is 2.7V.
Work around
Use the internal oscillator or an external clock
source if operation below 2.7V is required for the
frequency range supported by HS mode.

5. Module: CPU
5.1 Reset on Wake
If a wake from Sleep event occurs during the
execution of a Sleep command, the device may
reset. This Reset will be seen as a Power-on
Reset to the device.
Work around
1. Disable all asynchronous interrupt before
going to Sleep.
2. Make sure the timing of an asynchronous
interrupt will not happen during the execution
of the Sleep instruction.

6. Module: BOR
6.1 Current Draw in Sleep
With the BOR set to “Enabled during operation and
disabled during Sleep”, the device draws 2 A
more during Sleep than when the BOR is set to
“Disabled”.
Work around
None.

7. Module: WDT
7.1 CLRWDT Instruction after WDT Time-out
After a WDT Reset, the TO bit of the STATUS
register remains clear until a SLEEP instruction or
CLRWDT instruction is issued, then, the TO bit will
be set. If the CLRWDT instruction is issued within 20
S of the Reset, the TO bit will remain clear.
Work around
Wait at least 20 S after a WDT Reset before using
the CLRWDT instruction.

8. Module: Interrupts
8.1 Stack Push
The interrupt logic incorrectly pushes two
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.
