Field (Bits)
Description
REVISION
(7:0)
Revision number of the QSE device. Revision numbers start at 0.
Field (Bits)
Description
ENABLE_STAT_PINS
(7)
1
0
Enable StatOut and CtrlIn pin functionality
StatOut behaves like No Data In, and Ctrl In behaves like No Data Out.
PARITY_CHECK
(6)
1
0
Parity checks on cell header disabled.
Normal operation.
/NO_DATA_OUT
(5)
Current value at the /NO_DATA_OUT pin.
/NO_DATA_IN
(4)
Current value at the /NO_DATA_IN pin.
MULTICAST_MODE
(3)
1
0
External RAM present.
No external RAM.
CHIP_HARDWARE_RESET
(2)
1
Writing a one to this bit will put the chip is in hardware reset (except the
processor interface, which remains untouched).
Writing a zero to this bit will take the chip out of hardware reset.
0
Upon pin-reset, this bit comes up as a one. A zero must be explicitly written to
this bit before the chip can function normally.
SWITCH_MODE
(1)
1
0
Double switch mode.
Single switch mode.
Reserved
(1:0)
Write with a 0 to maintain future software compatibility.
