The Z86E72/73 microcontrollers incorporate special functions to enhance the Z8's
functionality in consumer and battery-operated applications.
The device is reset in one of the following conditions:

The Z86E72/73 microcontrollers address up to 16K/32 KB of internal program
memory, with the remainder being external memory
of program memory are reserved for the interrupt vectors. These locations contain
five 16-bit vectors that correspond to the five available interrupts. Addresses of
16K/32K consist of on-chip OTP. At addresses 16K or 32K and greater, the
Z86E72/73 microcontrollers execute external program memory fetches (see
“External Memory” on page 38).
