RAM Memory Map (Register Files)
There is a total of 1 KB of RAM available on the base Z8F082A device. Some of this RAM (from 080h
to 0EFh and 190h to 3FFh) is used by Zilog’s PIR technology. The remainder of the RAM from 000h
to 07Fh and 110h to 18Fh (256 bytes) is available to the application. The MCU Control Registers are
located at the top of memory from F00h to FFFh and are also available to the application. The area
from 400h to EFFh contains no device memory.
The PIR Motion Detection API is a series of registers located in RAM memory space from 0F0h to
10Fh. It is through these memory locations that configuration and status are passed between the PIR
technology and the user application. Advanced API registers are located from address 0F0h to 0FFh.
