Access Description
R/W Version
These bits define the current version of the Backplane Controller. If revisions are
required, these bits will change to reflect the latest version of the device. In general,
changes to bits 3 through 0 will reflect a minor revision and changes to bits 7 through
4 will reflect a major revision or different device type. Firmware should check this
register to determine the current capabilities of the device.
NOTE: The SSC050-01 and SSC050 currently utilize the same binary value in the Version
Register. However, the device type can be determined by performing the following
register write and read before configuring the device for normal operation. Write
a 15h to the Pulse Width Modulation Control Register at location 98h. Read this
register and check the result, if the register reads back 15h, the device is a
SSC050-01, if the register reads back 00h, the device is a SSC050.
