When the Block Lock bits of the CONSTAT register are
set to something other than BL1 = 0 and BL0 = 0, then
the “wiper position” of the DCPs cannot be changed - i.e.
DCP write operations cannot be conducted:
The factory default setting for these bits are BL1 = 0,
BL0 = 0.
IMPORTANT NOTE: If the Write Protect (WP) pin of the
X9520 is active (HIGH), then all nonvolatile write opera-
tions to both the EEPROM memory and DCPs are inhib-
ited, irrespective of the Block Lock bit settings (See "WP:
Write Protection Pin").
POR1, POR0: Power-on Reset bits – (Nonvolatile)
Applying voltage to V
CC
activates the Power-on Reset
circuit which holds V1RO output HIGH, until the supply
voltage stabilizes above the V
TRIP1
threshold for a
period of time, t
PURST
(See Figure 30).
The Power-on Reset bits, POR1 and POR0 of the
CONSTAT register determine the t
PURST
delay time of
the Power-on Reset circuitry (See "VOLTAGE MONI-
TORING FUNCTIONS"). These bits of the CONSTAT
register are nonvolatile, and therefore power-up to the
last written state.
The nominal Power-on Reset delay time can be selected
from the following table, by writing the appropriate bits to
the CONSTAT register:
The default for these bits are POR1 = 0, POR0 = 1.
V2OS, V3OS: Voltage Monitor Status Bits (Volatile)
Bits V2OS and V3OS of the CONSTAT register are
latched, volatile flag bits which indicate the status of the
Voltage Monitor reset output pins V2RO and V3RO.
At power-up the VxOS (x = 2,3) bits default to the value
“0”. These bits can be set to a “1” by writing the appropri-
ate value to the CONSTAT register. To provide consis-
tency between the VxRO and VxOS however, the status
of the VxOS bits can only be set to a “1” when the corre-
sponding VxRO output is HIGH.
Once the VxOS bits have been set to “1”, they will be
reset to “0” if:
—The device is powered down, then back up,
—The corresponding VxRO output becomes LOW.
