Power supply.
Power supply ground.
3.3V regulated output from MCU.
Reset input, active low.
With internal pull-up and schmitt trigger input.
External IRQ pin; with programmable internal pull-up and
schmitt trigger input.
Used for mode entry selection.
Crystal oscillator input.
Crystal oscillator output; inverting of OSC1 signal.
Analog power supply.
Analog power supply ground.
3.3V regulated output from MCU.
When the USB module is disabled, the PTE4 and PTE3 pins are
general-purpose bidirectional I/O port pins with 10mA sink capability.
Each pin is open-drain when configured as an output; and each pin
contains a software configurable 5k pullup to V
an input. The PTE4 pin can also be enabled to trigger the IRQ interrupt.
When the USB module is enabled, the PTE4/D– and PTE3/D+ pins
become the USB module D– and D+ pins. The USB D– pin contains a
1.5k software configurable pullup device to V

MC68HC908JG16 do not require termination, termination is
recommended to reduce the possibility of static damage.
