PIC24FJ256GA110 FAMILY
22. Module: Core (Code Protection)
When General Segment Code Protection has
been enabled (GCP Configuration bit is pro-
grammed), applications are unable to write to the
first 512 bytes of the program memory space
(0000h through 0200h). In applications that may
require the interrupt vectors to be changed during
run time, such as bootloaders, modifications to the
interrupt vector tables will not be possible.
Work around
Create two new interrupt vector tables, one each
for the IVT and AIVT, in an area of program space
beyond the affected region. Map the addresses in
the old vector tables to the new tables. These new
tables can then be modified as needed to the
actual addresses of the ISRs.

23. Module: SPI/PPS
The ALTRP/ASCK1 functionality is not supported
by the A3 revision of this part family.
Work around
None.

24. Module: Oscillator (LPRC)
The LPRC may not automatically restart following
BOR events (i.e., when supply voltage sags to
between the BOR and POR thresholds, then
returns to above the BOR level). When this hap-
pens, systems that use the LPRC clock may not
work. This includes the PLL, Two-Speed Start-up,
Fail-Safe Clock Monitor and the WDT.
Work around
For PLL issues: Select a non-PLL Clock mode as
the initial start-up mode, using the FNOSC Config-
uration bits (CW2<10:8>). After the application has
initialized, switch to a PLL Clock mode in software
using the NOSC bits (OSCCON<10:8>). Allow
10 microseconds to elapse between application
start-up and a software clock switch.
For WDT issues: Disable the WDT by programming
the FWDTEN bit (CW1<7>). After the application
has initialized, enable the WDT in software by
setting the SWDTEN bit (RCON<5>). Allow
10 microseconds to elapse between application
start-up and setting SWDTEN.
Affected Silicon Revisions
25. Module: CTMU (A/D Trigger)
The CTMU may not trigger an automatic A/D con-
version after the current source is turned off. This
happens even when the A/D trigger control bit,
CTTRIG (CTMUCON<8>), has been set.
Work around
Perform a manual A/D conversion by clearing the
SAMP bit (AD1CON1<1>) immediately after the
CTMU current source has been stopped.
Affected Silicon Revisions
26. Module: Output Compare
In PWM mode, the output compare module may
miss a compare event when the current duty cycle
register (OCxRS) value is 0000h (0% duty cycle)
and the OCxRS register is updated with a value of
0001h. The compare event is only missed the first
time a value of 0001h is written to OCxRS and the
PWM output remains low for one PWM period.
Subsequent PWM high and low times occur as
expected.
Work around
If the current OCxRS register value is 0000h, avoid
writing a value of 0001h to OCxRS. Instead, write
a value of 0002h. In this case, however, the duty
cycle will be slightly different from the desired
value.
