Point Grey Flea3 GigE - GPIO_XTRA_PIN: 1114 H-1144 H; TRIGGER_MODE: 830 H

Point Grey Flea3 GigE Technical Reference E Control and Status Registers
E.5 GPIO_XTRA_PIN: 1114h-1144h
These registers contain mode specific data for the GPIO pins. Units are ticks of a 1.024MHz clock.
Pin Register
0 GPIO_XTRA_PIN_0 1114h
1 GPIO_XTRA_PIN_1 1124h
2 GPIO_XTRA_PIN_2 1134h
3 GPIO_XTRA_PIN_3 1144h
Field Bit Description
Mode_Specific_1 [0-15] GPIO_MODE_4: Low period of PWM pulse (if Pwm_Pol = 0)
Mode_Specific_2 [16-31] GPIO_MODE_4: High period of PWM pulse (if Pwm_Pol = 0)
Format:
E.6 TRIGGER_MODE: 830h
Control of the register is via the ON_OFF bit and the Trigger_Mode and Parameter fields.
Field Bit Description
Presence_Inq [0]
Presence of this feature
0: Not Available, 1: Available
Abs_Control [1]
Absolute value control
0: Control with the Value field, 1: Control with the Absolute value CSR.
If this bit = 1, the value in the Value field is read-only.
[2-5] Reserved
ON_OFF [6]
Read: read a status
Write: ON or OFF for this feature
0: OFF, 1: ON
If this bit = 0, other fields will be read only
Trigger_Polarity [7]
Select trigger polarity (except for Software_Trigger)
0: Trigger active low, 1: Trigger active high
Trigger_Source [8-10]
Select trigger source: used to select which GPIO pin will be used for external trigger purposes.
Sets trigger source ID from Trigger_Source_Inq field of TRIGGER_INQ register.
Trigger_Value [11]
Trigger input raw signal value: used to determine the current raw signal value on the pin.
Read only
0: Low, 1: High
[8-11] Reserved
