3.6.2.2 Return Parameters

Table 3-97 describes the return parameters.

Table 3-97 Return Parameters
Parameter Bytes Description
Byte 1 DMD interface status
Byte 2 LED status
Byte 3 Internal interrupt status
Byte 4 Misc. status

All system status error bits are cleared when the read system status is read.

Table 3-98 Byte 1 Return Parameters
MSB Byte 1 – DMD Interface Status LSB
b7 b6 b5 b4 b3 b2 b1 b0
b(7:3) Reserved
b(2) DMD training error:
  • 0h: No error
  • 1h: Error
b(1) DMD interface error:
  • 0h: No error
  • 1h: Error
b(0) DMD device error:
  • 0h: No error
  • 1h: Error

The system sets the DMD device error for the following conditions:

  • The system cannot read the DMD device ID from the DMD.
  • The system-specified DMD device ID does not match the actual DMD device ID.

The system sets the DMD interface error when there are power management setup conflicts on this interface.

The system sets the DMD training error when the training algorithm cannot find a data eye that meets the specified requirements. For controller pins selected for training, DMD training will fail if less than 20 out of 50 continuous response values pass.
