15. Crystal oscillator and LazyClock
The ISP1161A has a crystal oscillator designed for a 6 MHz parallel-resonant crystal
(fundamental). A typical circuit is shown in
Figure 45
. Alternatively, an external clock
signal of 6 MHz can be applied to input XTAL1, while leaving output XTAL2 open. See
Figure 46
.
The 6 MHz oscillator frequency is multiplied to 48 MHz by an internal PLL. This
frequency is used to generate a programmable clock output signal at pin CLKOUT,
ranging from 3 MHz to 48 MHz.
In ‘suspend’ state the normal CLKOUT signal is not available, because the crystal
oscillator and the PLL are switched off to save power. Instead, the CLKOUT signal
can be switched to the LazyClock frequency of 100
±
50 % kHz.
The oscillator operation and the CLKOUT frequency are controlled via the
DcHardwareConfiguration register, as shown in
Figure 47
. The following bits are
involved:
CLKRUN switches the oscillator on and off
CLKDIV[3:0] is the division factor determining the normal CLKOUT frequency
NOLAZY controls the LazyClock signal output during ‘suspend’ state.
For details about the DC’s interrupt logic, see
Section 8.6.3
.
