Notes to Table 1–26:
(1) Applicable for true RSDS and emulated RSDS_E_3R transmitter.
(2) True RSDS transmitter is only supported at output pin of Row I/O (Banks 1, 2, 5, and 6). Emulated RSDS transmitter is supported at the output
pin of all I/O banks.
(3) t_LOCK is the time required for the PLL to lock from the end of device configuration.
