External Interface Module (EIM)
The following subsections provide information on the EIM.
4.6.6.1
EIM Signal Cross Reference
Table 36 is a guide intended to help the user identify signals in the External Interface Module Chapter of
the Reference Manual which are identical to those mentioned in this data sheet.
4.6.6.2
EIM Interface Pads Allocation
EIM supports16-bit and 8-bit devices operating in address/data separate or multiplexed modes. In some
of the modes the EIM and the NAND FLASH have shared data bus. Table 37 provides EIM interface
pads allocation in different modes.
4 NF17 is defined only in asymmetric operation mode.
NF17 max value is equivalent to max tRHZ value that can be used with NFC.
Taclk is “emi_slow_clk” of the system.
5
NF18 is defined only in Symmetric operation mode.
tDHR (MIN) is calculated by the following formula:
Tdl2 – (tREpd + tDpd)
where tREpd is RE propogation delay in the chip including I/O pad delay, and tDpd is Data propogation delay from I/O pad to
EXTMC including I/O pad delay.
NF18 max value is equivalent to max tRHZ value that can be used with NFC.
Taclk is “emi_slow_clk” of the system.
