DERIVATIVE INTERRUPTS
One derivative interrupt event is defined. It is controlled by
bits T2F and ET2I in the EPCR (see Tables 10 and 11).
The derivative interrupt event occurs when T2F is set. This
request is honoured under the following circumstances:
No interrupt routine proceeds
No external interrupt request is pending
The derivative interrupt is enabled
ET2I is set.
The derivative interrupt routine must include instructions
that will remove the cause of the derivative interrupt by
explicitly clearing T2F. If the derivative interrupt is not
used, T2F may directly be tested by the program.
Obviously, T2F can also be asserted under program
control, e.g. to generate a software interrupt.

TIMING
Although the PCA3354C; PCD3354A operate over a clock
frequency range from 1 MHz to 16 MHz, f
xtal
= 3.58 MHz
or 10.74 MHz will usually be chosen to take full advantage
of the frequency generator section.
10 RESET
In addition to the conditions given in the “PCD33xxA
Family”data sheet, all derivative registers are cleared in
the reset state.
11 IDLE MODE
In Idle mode, the frequency generator, the EEPROM and
the Timer 2 sections remain operative. Therefore, the
IDLE instruction may be executed while an erase and/or
write access to EEPROM is in progress.
12 STOP MODE
Since the oscillator is switched off, the frequency
generator, the EEPROM and the Timer 2 sections receive
no clock. It is suggested to clear both the HGF and the
LGF registers before entering stop mode. This will cut off
the biasing of the internal amplifiers, considerably
reducing current requirements.
The Stop mode
must not
be entered while an erase
and/or write access to EEPROM is in progress. The STOP
instruction may only be executed when EWP in EPCR is
zero. The Timer 2 section is frozen during Stop mode.
After exit from Stop mode by a HIGH level on CE/T0,
Timer 2 proceeds from the held state.
