PIR Engine Entry Points
The ZMOTION MCU Series is developed upon the Z8 Encore! XP-based Z8F082A MCU
with the added functionality of a motion detection (PIR) Engine. The PIR Engine is
located in the upper 4 KB area of the 8 KB device, leaving 4 KB of code space to the user
application. The PIR Engine operates in the background and is controlled and monitored
via an Application Programmer Interface (API). The API is a series of reserved registers
in memory.
There are two sections to the API: Standard API Registers and Advanced API Registers,
as described below.
Standard API Registers.
required by most applications. These include sensitivity control, motion detection/direc-
tion status and operational modes.
Advanced API Registers.
operation and allows it to be configured to support the pyroelectric sensor and lens being
used in the application.
Bit 7 of
to perform housekeeping operations. This bit must be set to 1, once per second by the user
application. The bit is checked and cleared during the EPIR_ADC_ISR routine.
There are two entry points to the PIR Engine that are accessed via two predefined macros
– one is an initialization macro that is used to start the Engine and the other is executed
upon every ADC interrupt. Both macros save and initialize the Register Pointer, perform a
call to the PIR Engine entry point and then restore the Register Pointer before returning
control to the application. It is the responsibility of the application software to execute
these macros at the appropriate time.
ePIR_INIT Macro.
mally only executed once and is used in conjunction with the

PIR Enable Pattern to the PIR Engine Enable Register, then execute this macro. ADC con-
versions are started by this macro.
