Zilog
FUNCTIONAL DESCRIPTION
The MCU incorporates the following special functions to
enhance the standard Z8 architecture to provide the user
with increased design flexibility.
RESET. The device is reset in one of three ways:
1. Power-On Reset
2. Watch-Dog Timer
3. Stop-Mode Recovery Source
Note: Having the Auto Power-on Reset circuitry built-in,
the MCU does not need to be connected to an external
power-on reset circuit. The reset time is Tpor. The MCU
does not re-initialize WDTMR, SMR, P2M, and P3M
registers to their reset values on a Stop-Mode Recovery
operation.

Program Memory. The MCU can address up to 4/8/16 KB
of Internal Program Memory (Figure 22). The first 12 bytes
of program memory are reserved for the interrupt vectors.
These locations contain six 16-bit vectors that correspond
to the six available interrupts. For EPROM mode, byte 12
(000CH) to address 4095 (0FFFH)/8191 (1FFFH)/16384
(3FFFH), consists of programmable EPROM. After reset,
the program counter points at the address 000CH, which
is the starting address of the user program.
In ROMless mode, the
64 KB of External Program Memory. The ROM/ROMless
option is only available on the 44-pin devices.
