Caution:
UART
Oscillator Control
All devices can be operated with the internal 5.54 MHz IPO. For applications that require
more processing power or a more accurate time base, an external crystal oscillator or
ceramic resonator can be used.
When using the 8-pin device, external oscillator support is limited to single pyro mode
only, since ANA3 (the ADC input for a second pyro sensor) is multiplexed with X
The 20- and 28-pin devices can be operated with an external oscillator in both single and
dual pyro modes.
No other changes or limitations are placed on oscillator control functions by the PIR
engine.
Flash Memory
The control registers associated with Flash memory are all available to the application.
Zilog’s PIR technology uses the value programmed into the Flash Frequency registers
(FFREQ) to determine its required sample timing. The Flash Frequency High (FFREQH)
and Flash Frequency Low Byte (FFREQL) registers must be programmed prior to initial-
izing the PIR engine. These two registers combine to form a 16-bit value, FFREQ. This
value is also used by the PIR engine to calculate the required sample rate of the ADC and
other functions. The 16-bit value for FFREQ is the System Clock Frequency in KHz and is
calculated using the following equation.
FFREQ[15:0] = {FFREQH[7:0],FFREQL[7:0]} = (System Clock
Frequency)/1000
8-Pin Device
20-Pin Device All external UART functions are available
28-Pin Device All external UART functions are available
Do not operate at frequencies lower than the IPO frequency while the PIR
engine is enabled or motion detection performance will be degraded.
/CTS0 is configured as ANA2 to support
the signal input from the Pyroelectric
sensor. It is therefore not available to the
user application. The UART is still able to
function correctly without /CTS when
CTSE in the U0CTL0 register set to 0.
