1. MUST BE LOW-LEAKAGE CAPACITOR (INSULATION RESISTANCE 30,000 M OR GREATER).
2. RESISTANCE AND CAPACITANCE BASED ON A TEST CIRCUIT CONSTRUCTED WITH A DAISHINKU DMX-38 32.768-kHz CRYSTAL.
The system clock in the SIM provides timing signals for the IMB modules and for an external peripheral
bus. Because MCU operation is fully static, register and memory contents are not affected when the
clock rate changes. System hardware and software support changes in the clock rate during operation.
The system clock signal can be generated in three ways. An internal phase-locked loop can synthesize
the clock from an internal or external frequency source, or the clock signal can be input from an external
source.
Following is a block diagram of the clock submodule.
The state of the clock mode (MODCLK) pin during reset determines the clock source. When MODCLK
is held high during reset, the clock synthesizer generates a clock signal from either a crystal oscillator
or an external reference input. Clock synthesizer control register SYNCR determines operating frequen-
cy and various modes of operation. When MODCLK is held low during reset, the clock synthesizer is
disabled, and an external system clock signal must be applied. When the synthesizer is disabled, SYN-
CR control bits have no effect.
A reference crystal must be connected between the EXTAL and XTAL pins to use the internal oscillator.
Use of a 32.768-kHz crystal is recommended. These crystals are inexpensive and readily available. If
an external reference signal or an external system clock signal is applied through the EXTAL pin, the
XTAL pin must be left floating. External reference signal frequency must be less than or equal to max-
imum specified reference frequency. External system clock signal frequency must be less than or equal
to maximum specified system clock frequency.
