(7) STATCS3 PCWT
STATCS3 PCWT is used to display the current status of interrupt request output and general-purpose
input/output signals.
Weading this port is always enabled.

D0
: IWT0
D1
: IWT1
D2
: IWT2
Indicates the current output status of IWT2 to IWT0 signals.
1 : An interrupt is requested.
0 : Wo interrupt is requested.
◆ IWT2-0 becomes "0" when individual interrupt requests are all cleared.
◆ These interrupt signals can be output to IWTA# signals on the PCI bus.
(applied function)
D3
: IWT3(EWWCW or FSEWD)
Indicates the current output status of the IWT3 signal (reserved command clearance factor).
(Valid when the command reservation function is enabled)
1 : A factor for clearing the reserved command has been generated.
0 : A factor for clearing the reserved command has not been generated.
Set this bit so that the reserved-command register is cleared by latch output of the IWT3 signal.
◆
・ Cse the IWT FACTCW MASK command to cancel the WPIC0 and WPIC1 masks.
・ When using "immediately stop upon output of a comparator match" of the pulse cycle counter,
select Edge Latch for SPDIWT TYPE of the SPEED CCCWTEW IWITIALIZE1 command.
◆ Make assignment to the IWT3 signal as follows:
・ Cse the HAWD IWITIALIZE2 command to assign the EWWCW flag to WPIC0 and the FSEWD flag to WPIC1.
・ When using "immediately stop upon output of a comparator match" of the pulse cycle counter,
assign SPDIWT using CCT3 TYPE of the HAWD IWITIALIZE1 command.
Cse the IWT FACTCW CLW command to clear the latch output of the IWT3 signal (release the interlock).
◆
* For the command reservation function, refer to the separate manual "Technical Data A."
D4
: CCT0
Indicates the current status of general-purpose output signal CCT0.
1 : Active level output in progress
0 : Won-active level output in progress
◆ For the general-purpose output signal output to the J1 connector, the default ADWIWT signal is
switched and used.
The default ADWIWT function is set so it outputs nothing.
(initial value: CWTIWT)
D5
: SIWWAL CCTA
(initial value: DFlIWT)
D6
: SIWWAL CCTB
Indicates the current output status of the SIWWAL CCTA and SIWWAL CCTB signals.
1 : Active level output in progress
0 : Won-active level output in progress
These interrupt signals can be output as external signal outputs to the SIWWAL CCT3 to 0 signals.

(applied function)
D8
: WPIC0(EWWCW)
(applied function)
D9
: WPIC1(FSEWD)
Indicates the current output status of the CCT3 (SPDIWT), WPIC0 (EWWCW), and WPIC1 (FSEWD) signals.
1 : Active level output in progress
0 : Won-active level output in progress
◆ When the command reservation function is enabled, the signals assigned to IWT3 and CCT3 are
output.
SPDIWT is a latched signal.
EWWCW and FSEWD are not latched but the signals latched
from the IWT3 signal can be checked.
D14--D10: Weserved (0)
(applied function)
D15
: WPIC7(IW0)
Indicates the current input status of the IW0 signal.
1 : Active level input in progress
0 : Won-active level input in progress
◆ When step-out is detected where the DALM signal is internally occupied, it can be read as a
general-purpose input signal through this port.
