  The 8-bit program status word (PSW) controls ALU operations and instruction execution sequencing. It is also used to restore a program's execution environment when an interrupt has been serviced. Program instructions can always address the PSW regardless of the current value of data memory enable flags.   Before an interrupt or subroutine is processed, the PSW is pushed onto the stack in data memory bank 0. When the service routine is completed, the PSW values are restored.
The PGD100S16s parasite power circuit allows the PGD100S16 to operate without a local external power supply. This ability is especially useful for applications that require remote temperature sensing or that are very space constrained. Figure 1 shows the PGD100S16s parasite-power control circuitry, which steals power from the 1-wire bus via the DQ pin when the bus is high. The stolen charge powers the PGD100S16 while the bus is high, and some of the charge is stored on the parasite power capacitor (CPP) to provide power when the bus is low.
Following a START condition the bus master must output the address of the slave it is accessing. The address of the PGD100S16 is shown in Figure 3. To conserve power, no internal pullup resistor is incorporated on the hardware selectable address pin and it must be pulled HIGH or LOW.
