REDUCED POWER MODES
9.1
Idle mode
In Idle mode, the Real-time clock, Counter 1 and
Counter 2 sections remain operative. In addition to the
description given in the “PCD33xxA family data sheet”
Idle mode may be left by a clock or a counter interrupt
event (see Section 8).
9.2
Stop mode
In Stop mode the Real-Time Clock, Counter 1, Counter 2
and the 32 kHz crystal oscillator sections remain operative
(depending on the state of the RUN and ECx bits in CLCR
and PCCR). In addition to the description given in the
“PCD33xxA family data sheet” Stop mode may be left by
a clock or a counter interrupt event (see Section 8).
10 INSTRUCTION SET RESTRICTIONS
RAM space is restricted to 224 bytes; care should be taken
to avoid accesses to non-existing RAM locations.
11 TIMING
The PCD3745A operates over a clock frequency range of
1 to 16 MHz.
12 RESET
In addition to the conditions given in the “PCD33xxA family
data sheet” all derivative registers are cleared in the reset
state.
13 SUMMARY OF CONFIGURATIONS

Notes
1.
2.
1 = standard I/O; 3 = push-pull Output.
Port state after reset: S = Set (HIGH) and R = Reset (LOW).
