Timing Signal Naming Convention
AC Characteristics
Timing symbols used in the timing diagrams within this document conform to the
following convention:
Exceptions to this convention include tACC and tAPA. tACC is a generic timing symbol
that refers to the aggregate initial-access delay as determined by tAVQV, tELQV, and
tGLQV (whichever is satisfied last) of the flash device. tAPA is specified in the flash
device’s data sheet, and is the address-to-data delay for subsequent page-mode reads.
