RESET pin is not fil-
tered.
Timers cannot be
cascaded.
ADC generates
extra interrupts.
Description
The RESET pin does not properly filter the input signal. The device may enter
Reset when the RESET pin is asserted for less than the specified four system
clock cycles (from NORMAL mode).
Workaround
Add external filtering to the printed-circuit board.
Setting the CSC bit (bit 4) of the Timer Control 0 Registers does not cascade
the timers as indicated in the specification.
Workaround
Timers can be cascaded using the Timer-Out and Timer-In functions through
the general-purpose I/O pins.
The ADC continues to generate interrupts in CONTINUOUS mode after the
first interrupt before the results of the next conversion is complete.
Workaround
Do not use CONTINUOUS mode. Use SINGLE-SHOT mode instead.
