FUNCTIONAL DESCRIPTION
(Continued)
Interrupts.
The Z86E04/E08 has six interrupts from six
different sources. These interrupts are maskable and pri-
oritized (Figure 15). The sources are divided as follows:
the falling edge of P31 (AN1), P32 (AN2), P33 (REF), the
rising edge of P32 (AN2), and two counter/timers. The In-
terrupt Mask Register globally or individually enables or
disables the six interrupt requests (Table 4).
When more than one interrupt is pending, priorities are re-
solved by a programmable priority encoder that is con-
trolled by the Interrupt Priority register. All Z86E04/E08 in-
terrupts are vectored through locations in program
memory. When an Interrupt machine cycle is activated, an
Interrupt Request is granted. This disables all subsequent
interrupts, saves the Program Counter and Status Flags,
and then branches to the program memory vector location
reserved for that interrupt. This memory location and the
next byte contain the 16-bit starting address of the interrupt
service routine for that particular interrupt request.
To accommodate polled interrupt systems, interrupt inputs
are masked and the interrupt request register is polled to
determine which of the interrupt requests needs service.
Note:
User must select any Z86E08 mode in Zilog's C12
ICEBOX
emulator. The rising edge interrupt is not sup-
ported on the Z86CCP00ZEM emulator.
