Signal
The S1D13705 uses CNF3 through CNF0 and BS# to allow selection of the bus mode and
other configuration data on the rising edge of RESET#. Refer to the S1D13705 Hardware
Functional Specification, document number X27A-A-001-xx for details.
The tables below show only those configuration settings important to the MPC821
interface. The settings are very similar to the ISA bus with the following exceptions:
• the WAIT# signal is active high rather than active low.
• the Power PC is big endian rather than little endian.
