IO Ports Tab

The following figure illustrates the IO Port Configuration within the IO Ports tab for setup of the IO port pins of the ATA8510 device at start-up time. These settings change when executing the ROM firmware or Flash application. For more details on the EEPROM port pin configuration, refer to the ATA8510/15 Industrial User's Guide (DS50003142). For more details about debug support, refer to the ATAN0096 ATA8510 Programmer's Guide.

Figure 1. IO Ports Tab

Note: The check boxes for Additional High Side Driver Active and Additional Low Side Driver Active activate an additional strong driver in conjunction with the default driver.

The preceding figure illustrates the default settings that define the IO pin configurations. To select and enable the alternative functions in other tabs, see the following table for port B, and Table 2 for port C. Enable these alternative settings within the ROM firmware or the Flash application and overwrite the initial settings from the IO ports configuration. For more details about the IO ports and the alternate functions, refer to the ATA8510/15 Industrial User's Guide (DS50003142).
