The transfer error status register (LTESR) indicates the cause of an error or event. LTESR, shown in

can clear but not set bits. A bit is cleared whenever the register is written, and the data in the corresponding
bit location is a 1. For example, to clear only the write protect error bit (LTESR[WP]) without affecting
other LTESR bits, 0x0400_0000 should be written to the register. After any error/event reported by
LTESR, LTEATR[V] must be cleared for LTESR to updated again.

to the following equation:
Example: For a 266-MHz system clock and a required service rate of 15.6 µs, given MRTPR[PTP] = 32, the
LURT value should be 128 decimal. 128/(266 MHz/32) = 15.4 µs, which is less than the required service
period of 15.6 µs.
Note that the reset value (0x00) sets the maximum period to 256 x MRTPR[PTP] system clock cycles.
