15.5.3.1.7
PTV is a 32-bit register written by the user to store the pause duration used when the eTSEC initiates an
IEEE 802.3 PAUSE control frame through TCTRL[TFC_PAUSE]. The low-order 16 bits (PT) represent
the pause time and the high-order 16 bits (PTE) represent the extended pause control parameter. The pause
time is measured in units of pause_quanta, equal to 512 bit times. The pause time can range from 0 to
65,535 pause_quanta, or 0 to 33,553,920 bit times. See
details.

Pause Time Value Register (PTV)
Extended pause control. This field allows software to add a 16-bit additional control parameter into the PAUSE
frame to be sent when TCTRL[TFC_PAUSE] is set. Note that current IEEE 802.3 PAUSE frame format
requires this parameter to be cleared.
Pause time value. Represents the 16-bit pause quanta (that is, 512 bit times). This pause value is used as
part of the PAUSE frame to be sent when TCTRL[TFC_PAUSE] is set. See
on page 15-154
