11.3.2.6 PAUSE Timer Value and Counter (PTIME)
Module Base + $8
Read: Anytime.
Write: Anytime except while PTRC is clear, but the user must not change this field while TXACT is set.
PTIME — PAUSE Timer Value and Counter
11.3.2.7 Interrupt Event (IEVENT)
When an event occurs that sets a bit in the interrupt event register, an interrupt is generated if the
corresponding bit in the interrupt mask registers is also set. Each bit in the interrupt event register is cleared
by writing a 1 to that bit position. A write of 0 has no effect.
Read: Anytime.
Write: Anytime (0s have no effect).

While the PTRC bit is set, the PTIME register controls the PAUSE duration parameter in units of slot
times (512 bit times) used in a transmission of a PAUSE control frame.
While PTRC bit is clear, the PTIME register indicates the current number of slot times (512 bit times)
remaining in a PAUSE period after the receiver accepts a PAUSE frame.
The value of the PAUSE timer counter is updated when a valid PAUSE control frame is accepted,
regardless of PTRC.
W
This flag is set when a full-duplex flow control PAUSE frame has been received. If not masked
(RFCIE is set), a receive flow control interrupt is pending while this flag is set.
This flag is set when the receive frame length exceeds the value of MAXFL. If not masked (BREIE is
set), a babbling receive error interrupt is pending while this flag is set.
R
R
1 = Transmitter stopped due to reception of a PAUSE frame.
0 = Normal transmit operation.
1 = A babbling receive error has been detected.
0 = No babbling receive errors have been detected.
