System Integration Module (SIM60)
6.7.1 Initial Configuration
The QUICC has three configuration (CONFIG) pins that are sampled during system (or
power-up) reset to select the initial size of the global chip select and whether the QUICC is
in the normal (CPU32+ enabled) mode or the slave (CPU32+ disabled) mode (see Table 6-
2).
See 6.10 Memory Controller for a description of the global chip select and 6.8 Slave (Disable
CPU32+) Mode for a description of slave mode. In normal mode, the global chip select can
initially assume the boot ROM port size to be either 8, 16, or 32 bits. In the slave mode, the
global chip select can be enabled with 8, 16, or 32 bits, or the global chip select can be dis-
abled. The global chip select would normally be disabled if another QUICC or processor was
providing the boot ROM chip select function.
6.7.2 Port D
If the user configures a 16-bit data bus by driving a zero voltage on the PRTY3 pin during
system reset, then the D0–D15 pins are not used as a data bus, but are referred to as port
D. At this time, port D is not available for general-purpose I/O or any other alternate function
on the QUICC. In the future, these pins may be defined to have an additional function in 16-
bit data bus mode.

Configuration Pins
All accesses to the QUICC internal RAM and registers (including
MBAR) by an external master are asynchronous to the QUICC
clock. Read and write accesses are with three wait states, and
DSACK is asserted by the QUICC assuming three-wait-state ac-
cesses.
