The tables below shows more details about the payload power failure. The Payload Power
Failure Registers 1 to 3 content is always 0, when the Payload Power Failure status (bit 7) of
Payload Power Failure State Register (
Table 5-49 ) is not set.
0xA VCCIO_VPP_E
NABLE Timeout (debug disabled) after 280ms. VCCIO and VPP
voltages are not good.
Other cause: One or more voltages have failed, which have
been already enabled and sampled good.
0xB VDDQ_ENABL
E Timeout (debug disabled) after 280ms. VDD voltages are not
good.
Other cause: One or more voltages have failed, which have
been already enabled and sampled good.
0xC VP12_ON Timeout (debug disabled) after 280ms. 12V or 5V aux
voltages are not good.
0xD VTT_ENABLE Timeout (debug disabled) after 280ms. VTT voltages are not
good.
Other cause: One or more voltages have failed, which have
been already enabled and sampled good.
0xE WAIT_100MS One or more voltages have failed, which have been already
enabled and sampled good.
