unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txCellSize
 

[22:16] Transmit expected cell size

Configures the cell size for the transmit module: Values between 52-64 are valid.

Definition at line 987 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txCOSET
 

[24] If enabled the HEC is Exclusive-ORĈed with the value 0x55 before being presented on the Utopia bus

  • 1 - Enable HEC ExOR with value 0x55
  • 0 - Use generated HEC value.

Definition at line 979 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txEvenParity
 

[26] Utopia Transmit Parity Mode

  • 1 - Even Parity Generated

  • 0 - Odd Parity Generated.

Definition at line 970 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txHEC
 

[25] Header Error Check Insertion Mode

Specifies if the transmit cell header check byte is calculated and inserted when set.

  • 1 - Generate HEC.
  • 0 - Disable HEC generation.

Definition at line 974 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txInterface
 

[30] Utopia Transmit Interface

The following encoding is used to set the Utopia Transmit interface as ATM master or PHY slave:

  • 1 - PHY
  • 0 - ATM

Definition at line 948 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txMode
 

[29] Utopia Transmit Mode

The following encoding is used to set the Utopia Transmit mode to SPHY or MPHY:

  • 1 - SPHY
  • 0 - MPHY

Definition at line 954 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txOctet
 

[28] Utopia Transmit cell transfer protocol

Used to set the Utopia cell transfer protocol to Octet-level handshaking. Note this is only applicable in SPHY mode.

  • 1 - Octet-handshaking enabled
  • 0 - Cell-handshaking enabled

Definition at line 959 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txParity
 

[27] Utopia Transmit parity enabled when set

TxEvenParity defines the parity format odd/even.

  • 1 - Enable Parity generation.
  • 0 - ut_op_prty held low.

Definition at line 965 of file IxAtmdAccCtrl.h.

unsigned int IxAtmdAccUtopiaConfig::UtTxConfig_::txPHYAddr
 

[4:0] When configured as a slave in an MPHY system this register specifies the physical address of the PHY
