EMI - Memory Interface
Subject to general operating conditions for V_DD, f_HCLK, and T_A unless otherwise specified.
The tables below use a variable which is derived from the EMI_BCONn registers (described
in the STR71x Reference Manual) and represents the special characteristics of the
programmed memory cycle.
