Enhanced Local Bus Controller
10.4.2.1
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 (LALE negated), 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.
