MCP2510
8.0
OSCILLATOR
The MCP2510 is designed to be operated with a crystal
or ceramic resonator connected to the OSC1 and
OSC2 pins. The MCP2510 oscillator design requires
the use of a parallel cut crystal. Use of a series cut crys-
tal may give a frequency out of the crystal manufactur-
ers specifications. A typical oscillator circuit is shown in
Figure 8-1. The MCP2510 may also be driven by an
external clock source connected to the OSC1 pin as
shown in Figure 8-2 and Figure 8-3.
8.1
Oscillator Startup Timer
The MCP2510 utilizes an oscillator startup timer (OST),
which holds the MCP2510 in reset, to insure that the
oscillator has stabilized before the internal state
machine begins to operate. The OST maintains reset
for the first 128 OSC1 clock cycles after power up,
RESET, or wake up from sleep mode occurs. It should
be noted that no SPI operations should be attempted
until after the OST has expired.
8.2
CLKOUT Pin
The clock out pin is provided to the system designer for
use as the main system clock or as a clock input for
other devices in the system. The CLKOUT has an inter-
nal prescaler which can divide FOSC by 1, 2, 4 and 8.
The CLKOUT function is enabled and the prescaler is
selected via the CANCNTRL register (see Register 9-
1). The CLKOUT pin will be active upon system reset
and default to the slowest speed (divide by 8) so that it
can be used as the MCU clock. When sleep mode is
requested, the MCP2510 will drive sixteen additional
clock cycles on the CLKOUT pin before entering sleep
mode. The idle state of the CLKOUT pin in sleep mode
is low. When the CLKOUT function is disabled (CAN-
CNTRL.CLKEN = ‘0’) the CLKOUT pin is in a high
impedance state.
The CLKOUT function is designed to guarantee that
thCLKOUT and tlCLKOUT timings are preserved when the
CLKOUT pin function is enabled, disabled, or the pres-
caler value is changed.

Note 1:
A resistor to ground may be used to reduce system noise. This may increase system current.
Note 2:
Duty cycle restrictions must be observed (see Table 12-2).
