Electrical Characteristics
4.9.3 External Interface Module (EIM)
The following subsections provide information on the EIM. Maximum operating frequency for EIM data
transfer is 104 MHz. Timing parameters in this section that are given as a function of register settings or
clock periods are valid for the entire range of allowed frequencies (0–104 MHz).
4.9.3.1 EIM Interface Pads Allocation
EIM supports 32-bit, 16-bit and 8-bit devices operating in address/data separate or multiplexed modes.
Table 40 provides EIM interface pads allocation in different modes.
