SGAmESSTR0 - SGAm Error Source Status Register 0
This register shows the status of each error source. The status is indicated
regardless of mask settings.
Access
This register can be read in 32-bit units.
Address
<SGAm_base> + 8
H
Initial value
0000 0000
H
This register is initialized by RESET only.
Note
This register is not tested by the self-diagnostic BIST.
Caution 1. The self-diagnostic BIST leads to setting (to 1) of the
SGAmESSTR0.SGAmSSE018 and SGAmESSTR0.SGAmSSE019 bits. They
should be cleared by software.
Caution 2. The generation of an internal reset may lead to setting of the
SGAmESSTR0.SGAmSSE006 bit (indicating detection of an ECC error in
flash memory) and the SGAmESSTR0.SGAmSSE007 bit (indicating detection
of an ECC error in flash memory, including when the error has been
corrected). For reliable detection of ECC errors, set the
SGAIRCFG0.SGAIRE006 and SGAIRCFG0.SGAIRE007 bits to suppress
internal resetting by the SGA (i.e. setting the bits to 0) and test the error source
flags in register CECCER.
