9.0 PERIPHERALS AND OTHERS
9.1 Core Timer
Core Timer provides the following features:
1. Real Time Interrupt (RTI)
2. Timer Overflow
3. COP watchdog timer
4. Power-on reset (POR)
Please refer to
SST65P542R Programming User’s
Manual
for programming information.
9.2 Carrier Modulator Transmitter (CMT)
SST65P542R integrates a carrier modulator transmitter for
supporting various encoding methods. The purpose of this
module is to reduce the loading of the MCU. Three major
functions are performed by this block: carrier generation,
modulation, and transmission.
Please refer to
SST65P542R Programming User’s Manual
for programming information.
9.3 Clock Input Options
Control connections for the 2-lead on-chip oscillator are the
OSC1 and OSC2 pins. OSC1 is input and OSC2 is output.
A crystal resonator, ceramic resonator, or external clock
signal can drive the oscillator.
9.4 Crystal/Ceramic Resonator
A crystal/ceramic oscillator circuit is shown in Figure 9-1. A
ceramic resonator instead of a crystal may be used to
reduce costs. It is recommended that the resonator and
capacitors be mounted as close to the pins as possible to
minimize output distortion.
Crystal manufacturer, supply voltage, and other factors
may cause circuit performance to differ from one appli-
cation to another. C1 and C2 should be adjusted
appropriately for each design.

9.5 External Clock Drive
If external clock source is provided, OSC1 is the clock input
and OSC2 is don’t connect. Leave OSC2 open.
