Signal Description
GNDA (4)
Address Bus Ground
GNDA is an isolated ground for sections of address bus I/O
drivers, and must be tied externally to all other chip ground connections. The user
must provide adequate external decoupling capacitors.
GNDC (2)
Bus Control Ground
GNDC is an isolated ground for the bus control I/O drivers,
and must be tied externally to all other chip ground connections. The user must
provide adequate external decoupling capacitors.
GNDD (4)
Data Bus Ground
GNDD is an isolated ground for sections of the data bus I/O
drivers, and must be tied externally to all other chip ground connections. The user
must provide adequate external decoupling capacitors.
GNDH (1)
Host Ground
GNDH is an isolated ground for the HI08 I/O drivers, and must be
tied externally to all other chip ground connections. The user must provide
adequate external decoupling capacitors.
GNDP (1)
PLL Ground
GNDP is ground dedicated for PLL use, and should be provided with
an extremely low impedance path to ground. VCCP should be bypassed to GNDP
with a 0.1 F capacitor located as close as possible to the chip package.
GNDP1 (1)
PLL Ground 1
GNDP1 is ground dedicated for PLL use, and should be provided
with an extremely low impedance path to ground.
GNDQ (4)
Quiet Ground
GNDQ is an isolated ground for the CPU logic, and must be tied
externally to all other chip ground connections. The user must provide adequate
external decoupling capacitors.
GNDS (2)
SSIs, GPIO, and Timers Ground
GNDS is an isolated ground for the SSIs, GPIO,
and Timers logic, and must be tied externally to all other chip ground connections.
The user must provide adequate external decoupling capacitors.
