(cont.)
Supervisory Diagnostic Registers
The Supervisory Function has four read-only registers that provide additional Supervisory
and WatchDog Timer status for debugging purposes. The contents of the registers are
described in the following tables.
Bit 7
Bit 6
Bit 5
Bit 4
Bit 3
Bit 2
Bit 1
Bit 0
Cen_resf
CEout
Stby
Vstby_on Cresb <1> Cresb <0>
RST_En
Deb_En
Sup-Pins (read only)
Deb_En
0 = RSTIN pin has no input filter.
1 = RSTIN pin is using a debounce filter.
RST_En
0 = PC5 pin serves as an active-high reset output.
1 = PC5 pin doesn’t serve as an active-high reset output.
Cresb<1:0>
0,0 = PC1 pin serves as an active-low, CMOS reset output.
0,1 = PC1 pin serves as an active-low, open-drain reset output.
1,0 = PC1 pin doesn’t serve as an active-low reset output.
1,1 = Reserved
Vstby_on
0 = PC4 pin serves as a battery backup mode indicator (high when Vstby > Vcc).
1 = PC4 is not used as a battery backup indicator.
VStby
0 = PC2 pin serves as a battery backup input.
1 = PC2 is not used as a battery backup input.
Ceout
0 = PC3 pin serves as an external memory select, backed-up by the battery input.
1 = PC3 is not used as a battery-backed, external memory select.
Cen_resf
0 = Bypass the Vtp reset digital sampler.
1 = Vtp reset is using the digital sampler.
