DESCRIPTION
Power for control logic, PLL and output buffers.
XTAL or external reference frequency input. This input
includes XTAL load capacitance and feedback bias for a 12 -
16 MHz crystal, nominally 14.31818 Mhz.
XTAL output which includes XTAL load capacitance.
Ground for logic, PLL and output buffers.
Processor clock outputs which are a multiple of the input
reference frequency as shown in the table above.
Frequency multiplier select pins. See table above. These inputs
have internal pull-up devices.
Selector for synchronous or asynchronous bus operation.
Bus clock outputs.
Fixed 48 MHz clock (with 14.318 MHz input).
Fixed 24 MHz clock (with 14.318 MHz input).
REF is a buffered copy of the crystal oscillator or reference
input clock, nominally 14.31818 Mhz.
