2.1.14 Power Signals
The following signals are used for power and ground to the QUICC.
2.1.14.1 VCCSYN AND GNDSYN. These pins provide power and ground to the clock syn-
thesizer. They should be bypassed to each other with a 0.1- F capacitor. See the system
clock generation description in Section 6 System Integration Module (SIM60) for more
details.
2.1.14.2 VCCCLK AND GNDCLK. These pins provide power and ground to the clock out-
put pins (CLKO1 and CLKO2). They should be bypassed to each other with a 0.1- F capac-
itor. See the system clock generation description in Section 6 System Integration Module
(SIM60) for more detail.
2.1.14.3 GNDS1 AND GNDS2. These two pins are special ground pins that, if used prop-
erly, allow more aggressive timing to be provided on certain system bus pins. These pins
include AS, CASx, and IPIPE. Section 10 Electrical Characteristics already shows the
aggressive timing; the user does not need to modify any values in the section. GNDS1 and
GNDS2 should be connected to a quiet ground source or to a low-noise ground plane.
2.1.14.4 VCC AND GND. These pins are the rest of the power and ground connections for
the QUICC.
2.1.14.5 NC4–NC1. These four pins should not be connected on the QUICC package. They
are reserved for future enhancements.

Configuration Pins
CONFIG1/
All CONFIG pins do have an internal pull-up resistor during re-
set. If a configuration other than the default (CONFIG2-1 = 111)
is desired, these pins should be driven by an active open collec-
tor device during the assertion of RESETH.
