Status Register
Structure Each status register (excluding the status byte
register) is divided into a number of register
structures:
 Condition register
 Positive transition register
 Negative transition register
 Event Register
 Event Enable Register
Condition
Registers The condition registers report the state of the
GSP-930. Condition registers can only be read.
PTR Registers The positive transistion registers are used to
filter for events that occur from a negative to a
positive transition.
NTR Registers The negative transition registers are used to
filter for events that occur from a positive to
negative transistion.
Event Registers The PTR/NTP registers dictate the type
transistion conditions that will set the
corresponding bits in the event registers. The
event registers can only be read. Reading an
event register will clear it.
Event Enable
Registers The event enable registers determine which
events in the corresponding event registers will
set the summary bits in a higher-order register.
