DevMstRst
Device master reset. When set high, all internal state machines in the TC block are
held in reset and all registers (except this bit) assume their default values.
6
0
DevLgcRst
Device logic reset. When set high, all internal state machines in the TC block are
held in reset but register values are unaffected.

0
EnStatLat
When set to 1, the one-second status latching is enabled. The value of the status
bits are the events which occurred between the last two one-second events. Any
events occurring after the last one-second event is not reflected when the status
register is read. Those events are reflected in the status register upon the next one-
second event. When a status register is read, the status is cleared and is not
updated until the next one-second event.
When set to 0, the one-second status latching is disabled. The value of a status
register is the events occurred since the last read of the status register.

0
EnCntrLat
When set to 1, the one-second counter latching is enabled. The value of the
counter is the number of events counted between the last two one-second events.
Any events occurring after the last one-second event is not reflected when the
counter is read. Those events are reflected in the counter upon the next one-
second event. When a counter is read, the count is cleared and is not updated until
the next one-second event.
When set to 0, the one-second counter latching is disabled. The value of a counter
is the number of events counted since the last read of the counter.

EnIntPin
Enables the MicroInt* output pin.
2–100

Reserved, set to zero.
0
OneSecOut
When set to 1, the OneSecIO pin is configured as an output. The pin provides a
one-second event pulse. The one-second event is generated internally of the
device. The event occurs after the device has counted 8000 periods of a 8 KHz
clock.
When set to 0, the OneSecIO pin is configured as an input. The one-second event
must be genetared externally, by pulsing the OneSecIO pin for low-high-low.
