9.4 Data Memory Write
Table 9-1. Data Memory Write Parameters
When using the AUTPOPTR1 or AUTOPTR2 to address external memory, the address of AUTOPTR1 is only active while either RD#
or WR# are active. The address of AUTOPTR2 is active throughout the cycle and meets the address valid time for which is based on
the stretch value.
