6.5 Register Description
The following section describes the Register which
are used to configure the Clock, Reset and PLVD.
6.5.1 Configuration Register.
CPU Clock Prescaler (CPU_CLK)
Configuration Register 46 (02Eh) Read/Write
Reset Value: 0000 0000 (00h)
Bit 7-6: Not Used
Bit 5-0: CPUCK5-0 CPU Clock Prescaler bits
The CPU Clock frequency is divided by a
factor described in the following table
6.5.2 Option Bytes.
Clock Mode (OSC_CR)
Option Byte 0 (00h)
Reset Value: 0000 0000 (00h)
Bit 7-2: Not Used
Bit 1-0: CKMOD1-0 Clock Mode
00: Internal Oscillator
01: External Clock or quartz
1x: External RC oscillator
External Clock Parameters (CLK_SET)
Option Byte 1 (01h)
Reset Value: 0000 0000 (00h)
Bit 7-3: Not Used
Bit 2-0: CKPAR2-0 Oscillator Gains
These three bits enable/disable the loop
gains when a external clock or quartz are
used
for
generating
the
clock.
The
following
table
decribes
the
possible
configuration options. Table 6.2 illustrates
the reccomended values for the most
common frequencies used, time to start the
oscillations and the settling time to have a
duty cycle of 40%-60% (at steady state it is
50%).
Warning: If an External Clock is used instead of a
quartz or ceramic resonator, it is reccomended that
no gain be enabled (CKPAR2-0=000) in order lo
lower the current consuption.
