GTM Transceiver RX Reset in Response to Completion
of Configuration
The RX reset sequence shown in
is not automatically started to follow global GSR.
These conditions must be met:
1. RXRESETMODE must be set to sequential mode.
2. GTRXRESET must be used.
3. All RXPMARESETMASK and RXPCSRESETMASK bits should be set to High.
4. GTRXRESET cannot be driven Low until the associated PLL is locked.
5. Ensure that GTPOWERGOOD is High before releasing PLLRESET and GTRXRESET.
