Figure 12–7. Remote System Configuration Control Register
Table 12–4 shows the content of the control register upon POR.
The status register specifies the reason why re-configuration has occurred
and determines if the re-configuration was due to a CRC error, nSTATUS
pulled low due to an error, the device core caused an error, nCONFIG was
reset, or the watchdog timer timed-out. Figure 12–8 and Table 12–5
specify the content of the status register.
