INT_CHAN_3 should normally be fixed in a low-level state and generate a high_pulse to interrupt
the PC.
Cin1 can be 2M/32768Hz programmable as is given below: (Refer to
Sec. 6.3.9
)
CTRL_D0=0
Cin1=2 M clock source
CTRL_D0=1
Cin1=32768 Hz clock source
EN3 can be used to enable/disable the INT_CHAN_3 as follows: (Refer to
Sec. 6.3.4
)
EN3=0
INT_CHAN_3= Disabled
EN3=1
INT_CHAN_3= Enabled
INV3 can be used to invert/non-invert the Cout0 as follows: (Refer to
Sec. 6.3.6
)
INV2=3
INT_CHAN_3=invert (Cout2)
INV2=3
INT_CHAN_3=non-invert (Cout2)
Refer to the following demo program for more information:
Operating System: DOS
