Product specification
Digital telephone answering machine chip
PCD6001
Table 6 shows the input clock selection in the analog
section of the chip. Note that for 3.456 and 3.58 MHz
crystal input clock, no clock division is done prior to
inputting it to the PLL. After reset the input clock division
rate is by default 1. This means that applications using an
input clock frequency other than 3.456 or 3.580 MHz, will
have to set the proper division rate, after system start-up.
Otherwise proper functionality of the analog blocks is not
guaranteed.
Table 7 shows the microcontroller clock frequencies. In
Emergency mode (bit 7 of CKCON reset), the EMG_CLK
is input directly to the microcontroller. The values of
CKCON bits 2 and 3 are then irrelevant. Note that
Emergency mode operation is only designed for start-up
and POTS mode condition. Peripheral blocks (such as the
CODECs and the IOM block) are not guaranteed to work
when CKCON bit 7 is reset.
Table 6
Input clock selection
Note
1.
The PCD6001 timing system is based on the 3.456 MHz (or multiples) input clock frequency. In order to be able to
use the low cost 3.58 MHz crystal or ceramic resonator, a clock frequency correction is needed for some blocks
(RTC, CODEC and IOM). IOM will only operate in Master mode.

Microcontroller clock selection
Notes
1.
2.
6 clocks/cycle.
If the PLL is switched off when not in Emergency mode, the selected clock would not be available. The micro would
hang up. Before CKCON.7 is set to logic 1, SYMOD.5 must be set to logic 1 to activate the PLL.
