FUNCTIONAL DESCRIPTION (Continued)
Z86E30/E31/E40
Z8 4K OTP Microcontroller
Interrupts. The MCU has six different interrupts from six
different sources. The interrupts are maskable and priori-
tized (Figure 28). The six sources are divided as follows:
four sources are claimed by Port 3 lines P33–P30) and two
