37.This pin is only an output in FIFO mode when used as Rx Flow Control.
38.This pin functions as cfg_dram_type[0 or 1] at reset. Note: This pin must be valid before HRESET assertion in device sleep
39. Should be pulled to ground if unused (such as in FIFO, MII and RMII modes).

41. The phase between the output clocks TSEC1_GTX_CLK and TSEC2_GTX_CLK (ports 1 and 2) is no more than 100 ps.
42. For systems which boot from Local Bus (GPCM)-controlled flash, a pullup on LGPL4 is required.
Special Notes for Single Core Device:
S1 . Solder ball for this signal will not be populated in the single core package.

S3 . This pin should be pulled to GND for the single core device.
S4 . No special requirement for this pin on single core device. Pin should be tied to power supply as directed for dual core.
