Legend: y = Value set from Configuration bits on POR
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-16 Unimplemented: Read as ‘0
bit 15 ON: Deadman Timer Module Enable bit
(1)
1 = Deadman Timer module is enabled
0 = Deadman Timer module is disabled
The reset value of this bit is determined by the setting of the FDMTEN bit (DEVCFG1<3>).
bit 13-0 Unimplemented: Read as ‘0
Note 1: This bit only has control when FDMTEN (DEVCFG1<3>) = 0.

bit 15-8 STEP1<7:0>: Preclear Enable bits
01000000 = Enables the Deadman Timer Preclear (Step 1)
All other write patterns = Set BAD1 flag.
These bits are cleared when a DMT reset event occurs. STEP1<7:0> is also cleared if the
STEP2<7:0> bits are loaded with the correct value in the correct sequence.
bit 7-0 Unimplemented: Read as ‘0
