Chapter 8. Support
Expansion Write Enable (0:1) (L). These are buffered GPCM Write
Enable lines (0:1). They are meant to qualify writes to GPCM
controlled 8/16 data bus width memory devices. This to provide
eased access to various communication transceivers.
EXPWE0# controls EXPD(0:7) while EXPWE1# controls
EXPD(8:15). These lines may also function as UPM controlled
Byte Select Lines, which allow control over almost any type of
memory device.
Digital Ground. Connected to main GND plane of the ADS.
Expansion General Purpose Lines (0:5) (L). These are buffered
GPL(0:5)# lines which assist UPM control over memory device if
necessary. These are output only signals and therefore, do not
support H/W controlled UPM waits.
Digital Ground. Connected to main GND plane of the ADS.
Expansion address latch enable (H). This is the buffered
PowerQUICC II‘s ALE, provided for expansion board’s use.
Expansion control line 0. This line is a buffered version of
PowerQUICC II’s BCTL0 (Bus Control Line 0) which serves as
W/R#, provided for expansion board’s use.
