3.5.57. PKT_FIELD_3_CRC_CONFIG
 Summary: Field 3 CRC configuration bits.
 Purpose:

Field 3 CRC configuration bits.
 Property: 0x1218
 Default: 0x00
 Fields:

RESERVED[1:0] - default:0x0 Reserved.

SEND_CRC32 - default:0

0x1 = Transmit CRC at the end of this field

CHECK_CRC32 - default:0

0x1 = Check CRC at the end of this field. If PH_FIELD_SPLIT is set, this bit is ignored.

CRC32_ENABLE - default:0
0x1 = Enable CRC over this field.

3.5.58. PKT_FIELD_4_LENGTH_12_8
 Summary: Byte 1 of field length
 Purpose:

This property specifices the length of this field in bytes.

A value of zero in this property means that the field is not used.

If the field is programmed as a variable length field, this property sets the maximum length of the field.

Used along with byte 0 property.
 Property: 0x1219
 Default: 0x00
 Fields:

FIELD_4_LENGTH_12_8[4:0] - default:0x00
0x0 = Bit 8 to 12 of the field length.
