Frame Checker Enable Register

Device Address: 0x1F; Register Address: 0x8001, Reset: 0x0001, Name: FC_EN

This register is used to enable the frame checker. The frame checker analyzes the received frames from either the MAC interface or the PHY

(see the FC_TX_SEL register) to report the number of frames received, CRC errors, and various other frame errors. The frame checker frame

and error counter registers count these events.

Frame Checker Interrupt Enable Register

Device Address: 0x1F; Register Address: 0x8004, Reset: 0x0001, Name: FC_IRQ_EN

This register is used to enable the frame checker interrupt. An interrupt is generated when a receive error occurs. Enable the frame

checker/generator interrupt in the PHY_SUBSYS_IRQ_MASK register. Set the MAC_IF_FC_FG_IRQ_EN bit.

The status can be read via the MAC_IF_FC_FG_IRQ_LH bit in the PHY_SUBSYS_IRQ_STATUS register.

Frame Checker Transmit Select Register

Device Address: 0x1F; Register Address: 0x8005, Reset: 0x0000, Name: FC_TX_SEL

This register is used to select the transmit side or receive side for frames to be checked. If set, frames received from the MAC interface to

be transmitted are checked. The frame checker can be used to verify that correct data is received over the MAC interface and is also useful

if remote loopback is enabled (see the MAC_IF_REM_LB_EN bit in the MAC_IF_LOOPBACK register) because it can be used to check the

received data after it is looped back at the MAC interface.

1: check frames from the MAC interface to be transmitted by the PHY.

0: check frames received by the PHY from the remote end.
