Internal Logic Power—These lines supply a quiet power source to the oscillator
circuits and the mode control and interrupt lines. Ensure that the input voltage to
this line is well-regulated and uses an extremely low impedance path to tie to the
V
package to connect between the V
Address Bus Power—These lines supply power to the address bus.
Data Bus Power—These lines supply power to the data bus.
Bus Control Power—This line supplies power to the bus control logic.
Host Interface Power—These lines supply power to the Host Interface logic.
Serial Interface Power—This line supplies power to the serial interface logic (SCI
and SSI).
Internal Logic Ground—These lines supply a quiet ground connection for the
oscillator circuits and the mode control and interrupt lines. Ensure that this line
connects through an extremely low impedance path to ground. Use a 0.1 F bypass
capacitor located as close as possible to the chip package to connect between the
VCCQ line and the GNDQ line.
Address Bus Ground—These lines connect system ground to the address bus.
Data Bus Ground—These lines connect system ground to the data bus.
Host Interface Ground—These lines supply ground connections for the Host
Interface logic.
