MC68HC05SU3A
GENERAL DESCRIPTION

1.2
Mask Options
The following mask options are available:
RC or Crystal Oscillator (see Section 2.2). The default is crystal option.
IRQ pull-up resistor — enabled or disabled.
Power-On Reset delay — Table 1-1 shows available options. The default value is 4096
cycles.
Power-On Reset Slow mode. If enabled, the device goes into Slow mode directly upon
power-on reset. The bus frequency is 16 times slower than the normal mode. Thus, the
power-on reset delay will also be 16 times longer. The default setting is “Slow mode”
disabled.
