L2 error detection, reporting, and injection allow flexible handling of ECC and parity errors in the L2 data
and tag arrays. When the device detects an L2 error, the appropriate bit in the error detect register
(L2ERRDET) is set. Error detection is disabled by setting the corresponding bit in the error disable register
(L2ERRDIS).
The address and attributes of the first detected error are also saved in the error capture registers
(L2ERRADDR, L2ERRATTR, L2CAPTDATAHI, L2CAPTDATALO, and L2CAPTACC). Subsequent
errors set error bits in the error detection registers, but information is saved only for the first one. Error
reporting (by generating an interrupt) is enabled by setting the corresponding bit in the error interrupt
enable register (L2ERRINTEN). Note that the error detect bit is set regardless of the state of the interrupt
enable bit. When an error is detected, if error detection is enabled the L2 cache/SRAM always asserts an
internal error signal with read data to prevent the L1 caches and architectural registers from being loaded
with corrupt data. If error detection is disabled, the detected error bit is not set and no internal signal is
asserted.
The L2 error detect register (L2ERRDET) is implemented as a bit-reset type register. Reading from this
register occurs normally; 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 bit 6 and not
affect any other bits in the register, the value 0x0200_0000 is written to the register.
Note that in SRAM mode, if a non–cache-line read or write transaction is not preceded by a cache-line
write, an ECC error occurs; such a non–cache-line write transaction cannot be allocated in the L2.
