30 / 70 page Pin Description III-20 Slave Controller – ET1200 Hardware Description 3.7.5 PDI[7:0] Signals Table 24 shows the PDI[7:0] signals. The direction of all PDI pins depends on the PDI configuration stored in the SII EEPROM. Table 24: PDI pins Pin Pin PDI, C25ENA=0, CLK_MODE=00 PDI, C25ENA=1, CLK_MODE/=00 Internal PU/PD Name Dir.

The PDI selection and PDI signal pinout is subject to restrictions introduced by the port configuration. Digital I/O and SPI PDI are available in any configuration – although the I/O width can be reduced depending on the configuration. The MII bridge port PDIs is only available in chip mode 00. Refer to PDI descriptions for further PDI and PDI signal descriptions. The SPI PDI supports additional general purpose output signals, which are not part of the SPI PDI description: GPO[x] General purpose output signals. |
