memory cycle are taken from ORn. These attributes include the CSNT, ACS, XACS, SCY, TRLX, EHTR
and SETA fields.

The basic GPCM read timing parameters that may be set by the ORn attributes are shown in
The read access cycle commences upon latching of the memory address and concludes when LBCTL
returns high to turn the local bus around for a subsequent address phase. Read data is captured by eLBC
on the falling edge of TA. LOE and LCSn negate high simultaneously, in some cases before the end of the
read access to provide additional hold time for the external memory.
