The LBC has the following registers for error management:
LTESR, shown in
however, write operations 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. Note
that LTEATR[V] bit has to be cleared to register subsequent errors in LTESR.

The transfer error status register (LTESR) indicates the cause of an error.
The transfer error check disable register (LTEDR) is used to enable (and disable) error checking.
The transfer error check interrupt register (LTEIR) enables reporting of errors through an interrupt.
The transfer error attributes register (LTEATR) captures source attributes of an error.
The transfer error address register (LTEAR) captures the address of a transaction that caused an
error.

to the following equation:
Example: For a 266-MHz system clock and a required service rate of 15.6 µs, given PTP = 32, the LSRT
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 × MRTPR[PTP] system clock cycles.
