DESCRIPTION 
CTOUT2PE 
rw 
CT_OUT2 (J7.2) pulse extender
0 = disabled (default)
1 = enabled, extend selected signal by 100nSec approximately. 
CTOUT2SEL[1:0] 
rw 
000 
CT_OUT2 (J7.2) source select
000 = 8254 CT2 output (default)
001 = Digital Output, DOUT5. Reference Digital Outputs Register.
010 = Analog Input ADC-sample / ADC-Burst sample pulse
011 = Active ADC Sampling
100 = Analog Input Frame Timer
101 = Interrupt Counter Increment
110 = zero
111 = IOCHRDY 
CTOUT0PE 
rw 
CT_OUT0 (J7.3) pulse extender
0 = disabled (default)
1 = enabled, extend selected signal by 100nSec approximately. 
CTOUT0SEL[1:0] 
rw 
000 
CT_OUT0 (J7.3) source select
000 = 8254 CT0 output (default)
001 = Digital Output, DOUT4. Reference Digital Outputs Register.
010 = Trigger delay end pulse
011 = Trigger delay start pulse
100 = Interrupt Threshold Counter maximum reached
101 = Active ADC Sampling
110 = ADC Data MSB address decode
111 = Interrupt 

This register is used to configure the CT_OUT2 (J7.2) and the CT_OUT0 (J7.3) outputs. In other words, these outputs are now generalized and various signals can be routed to these outputs.
