Notes to
Table 8–22
(1) The remote system upgrade master state machine is in factory configuration.
(2) The remote system upgrade master state machine is in application configuration.
The previous two application configurations are available in the previous state
registers (previous state register 1 and previous state register 2), but only for
debugging purposes.
Table 8–23
lists the contents of previous state register 1 and previous state register 2 in
the status register. The status register bit in
3-bit register. The previous state register 1 and previous state register 2 have the same
bit definitions. The previous state register 1 reflects the current application
configuration and the previous state register 2 reflects the previous application
configuration.
