Description
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
0 = No action
1 = Do Software Reset.
0 = No action
1 = Release System Reset of External Peripherals.
0 = No action
1 = Do System Reset of External Peripherals.
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Reset Cause register:
00 = Cause is External System Reset, RESET_IN_N.
01 = Cause is Software System Reset.
10 = Cause is External System Reset, POR_IN_N
11 = Cause is watchdog time-out.
Note if multiple resets occur then only the one that is highest in the
above order will be registered. As an example RESET_IN_N (00)
and POR_IN_N (10) are both asserted. A read would return “10”
Value to count to in order to either assert an interrupt (interrupt
mode) or a reset (non interrupt mode)
Value to count to after the interrupt is asserted before asserting the
system reset
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
1: watchdog interrupt is asserted
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
1: interrupt enabled
0: interrupt NOT enabled
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
