This field is used to force continuous training on the SPI-4 ingress status interface.
0:Normal status channel operation.
1:Force continuous training on the SPI-4 ingress status interface.
This field is used to insert the number of DIP-2 errors on the SPI-4 ingress status
interface programmed into the I_DIP_NUM field. After the DIP-2 errors are inserted,
the I_ERR_INS field will clear itself.
0:Normal status channel operation.
1:Insert DIP-2 errors on the SPI-4 ingress status interface.
This field is used to program the number of DIP-2 errors to be inserted when the
field I_ERR_INS is set to ‘1’. The number programmed should be less than 16.
This field enables or disables automatic alignment for the incoming LVDS data bits
in the data path. This register is used for test purposes.
0:Auto alignment is used for test mode.
1:Auto alignment is automatic.
The I_CSW_EN field is used to enable the switching of active calendars and
works together with CAL_SEL.Refer to Table 66 for calendar selection.
This field is used to select calendar_0 or calendar_1. This bit is valid only if
I_CSW_EN is set to 1. Refer to Table 66 for calendar selection.
This field describes the DIP-2 computation method based on the setting of
I_CSW_EN.Please refer toTable 67 for bit setting.
