1.4 Mask Options
Eight mask options are available to select the pullup/interrupts on port B
on a pin-by-pin basis.
There are also four mask options for:
1. IRQ (edge-sensitive only or edge- and level-sensitive)
2. CLOCK (crystal or RC)
3. COP (enable or disable)
4. STOP (enable or disable).
1.5 Functional Pin Description
The MC68HC05C8A is available in a 40-pin DIP (see Figure 1-2),
42-pin SDIP (see Figure 1-3), 44-pin PLCC (see Figure 1-4), and
44-pin QFP (see Figure 1-5). The following paragraphs describe the
general function of each pin.
NOTE:
A line over a signal name indicates an active low signal. For example,
RESET is active high and RESET is active low. Any reference to voltage,
current, resistance, capacitance, time, or frequency specified in the
following paragraphs will refer to the nominal values. The exact values
and their tolerance or limits are specified in Section 13. Electrical
