CSTAT Field Bit Requirements

5.2 CSTAT Field Bit Requirements

Texas Instruments specifies that some bits in the CSTAT field should be set to 1, but tells you to ignore them. This is because these bits are ignored by the adapter. The ThunderLAN CSTAT is very much like that in TI380 products. Bit 12 in ThunderLAN corresponds to bit 3 in the TI380 CSTAT FRAME_END bit. Bit 13 in ThunderLAN corresponds to bit 2 in the TI380 CSTAT FRAME_START bit. We define bits 12 and 13 as 1, since that is the way that they would appear on TI380 drivers where one list handles one frame only. ThunderLAN was designed so that a TI380 driver could be easily modified to become a ThunderLAN driver.

Texas Instruments has reserved the use of these bits for future applications. Setting these bits to any other value than 1 may cause problems with later ver- sions of ThunderLAN.
