Notes:
A) The Z89332 should not be operated for extended periods with the crystal oscillator disconnected, except in the defined
power-down modes. In the event that the Z89332 is operated with the oscillator disconnected, the device may draw higher
than typical current.
B) Each line of the on-screen display can consist of any number of characters, up to a maximum of 30 characters.
