(SyncManager) and data mapping (FMMU). Each FMMU performs bitwise mapping of logical EtherCAT® system addresses to physical device addresses. The scope of this document is to describe the EVB-LAN9252-DIG-IO setup, which sup- ports a Digital I/O Interface and corresponding jumper configurations. The LAN9252 is connected to an RJ45 Ethernet jack with integrated magnetics for 100BASE-TX con- nectivity.
80ms. 2.2.3 GPIO Reset The EVB-LAN9252-DIG-IO provides the option to reset the LAN9252 through a PIC GPIO pin [95(RG14)]. The SW10 switch is used for this selection, as shown in Table 2-1.
The EVB-LAN9252-DIG-IO utilizes an external 25Mhz 25ppm crystal from Cardinal Components Inc. (P/N: CSM1Z-A5B2C5-40-25.0D18-F). CONFIGURATION The following sub-sections describe the various board features and configuration set- tings. A top view of the EVB-LAN9252-DIG-IO is shown in Figure 2-1.

EVB-LAN9252-DIG-IO EtherCAT® DIG I/O User’s Guide 2.4.3 EEPROM Switch The EVB-LAN9252-DIG-IO utilizes 0x50 (7-bit) I C slave addressing. The SW3 switch can be used to select the A0, A1, and A2 address bits, as shown in Figure 2-2 and Table 2-11. The eighth bit of the slave address determines if the master device wants to read or write to the EEPROM (24C512).
This pin is the external data latch signal. The input data is sampled each time a rising edge of LATCH_IN is recognized. By default, this signals is pulled high through R131and can be made low using switch SW6. Preliminary 2014 Microchip Technology Inc. DS50002332A-page 19...
