15.5.3.10.4 Timer PTP Packet Event Register (TMR_PEVENT)
The eTSEC precision timer logic can generate interrupts upon the capture of a timestamp due to either
transmission or reception of a frame. If an event occurs and its corresponding enable bit is set in the event
mask register (PEMASK), the event also causes a hardware interrupt at the PIC. A bit in the timer event
register is cleared by writing a 1 to that bit position. Figure 15-107 describes the definition for the
TMR_PEVENT register.

15.5.3.10.5 Timer Event Mask Register (TMR_PEMASK)
Timer event mask register. The event mask register provides control over which possible interrupt events
in the TMR_PEVENT register are permitted to participate in generating hardware interrupts to the PIC.
All implemented bits in this register are R/W and cleared upon a hardware reset.
