19. Module: Memory (Program Space
Visibility)
When accessing data in the PSV area of data
RAM, it is possible to generate a false address
error trap condition by reading data located pre-
cisely at the lower address boundary (8000h). If
data is read using an instruction with an
auto-decrement, the resulting RAM address will be
below the PSV boundary (i.e., at 7FFEh); this will
result in an address error trap.
This false address error can also occur if a 32-bit
MOV
instruction is used to read the data at location,
8000h.
Work around
Do not use the first location of the PSV page
(address 8000h). The MPLAB C Compiler (v3.11 or
later) supports the option, “-merrata=psv_trap”,
to prevent it from generating code that would cause
this erratum.

20. Module: ICSP
The
ICSP/ICD
port
pair,
PGEC3/PGED3
(RB5/RB4), cannot be used to read or program the
device.
Work around
Use either PGEC2/PGED2 or PGEC1/PGED1.
Affected Silicon Revisions
21. Module: Core (Instruction Set)
If an instruction producing a Read-After-Write stall
condition is executed inside a REPEAT loop, the
instruction will be executed fewer times than was
intended. For example, this loop:
repeat #0xf
inc [w1],[++w1]
will execute less than 15 times.
Work around
Avoid using REPEAT to repetitively execute
instructions that create a stall condition. Instead,
use a software loop using conditional branches.
The MPLAB C Compiler will not generate REPEAT
loops that cause this erratum.

22. Module: RTCC
Under certain circumstances, the value of the
Alarm Repeat Counter (ALCFGRPT<7:0>) may be
unexpectedly decremented. This happens only
when a byte write to the upper byte of ALCFGRPT
is performed in the interval between a device
POR/BOR, and the first edge from the RTCC clock
source.
Work around
Do not perform byte writes on ALCFGRPT,
particularly the upper byte.
Alternatively, wait until one period of the SOSC
has completed before performing byte writes to
ALCFGRPT.
