RST_MASK1
04Bh
Function
The RST_MASKn registers are used to block reset to a particular device, independent of the general reset sequencer. As long
as a bit is set to 1, the reset signal to that device or devices will be blocked.
RST_MASKn bits have the same bit definition as their counterparts in RST_FORCEn; refer to Table 5-53 for details.
Note that RST_MASK bits are cleared on AUX reset, and so are usually only cleared by software. This is very different from the
RST_FORCE registers.
