DI digital input register
Offset
Address
Name
R/W
Explain
0x0200
DiReady
R/W
DI function configuration completion flag, 1 means
to start waiting for triggering, and 0 means that the
configuration has not been completed.
0x0204
Di acquisition
mode
R/W
0: Software-initiated single point read
1. Hardware timing limited number of acquisitions
2. Hardware timing continuous acquisition
0x0208
Di sampling
period
R/W
Di acquisition period, in 20ns.
Di acquisition actual period = this register value *
20ns
0x020C
Di limited number
of collection points
R/W
Di collects points for a limited number of times.
0x0210
Di acquisition
clock source
R/W
0: external clock.
1: internal clock.
0x0214
Di trigger source R/W See the trigger source chapter later.
0x0218
Di single point
reading
R
Read the current Di status.
0x021C
Di interrupt level R/W
Set the level at which Di generates an interrupt. Each
bit represents the interrupt level of the corresponding
channel, 1 represents the high-level interrupt and 0
represents the low-level interrupt.
0x0220
Di interrupt
channel
R/W
Channels that can generate interrupts. Each bit
represents the interrupt level of the corresponding
channel, 1 represents the high-level interrupt and 0
represents the low-level interrupt.
0x0224
Di sensitivity
count value
R/W
Set the Di sensitivity in 20ns.
Di actual sensitivity = this register value * 20ns
0x0228
Di counter enable R/W 1 means to start the counting function, and 0 means
to turn it off.
0x022C
Di counting edge R/W
Set whether the Di counter is rising edge counting or
falling edge counting. Each bit represents the
corresponding channel, 1 represents the rising edge
count, and 0 represents the falling edge count.
0x0230
Di0 counter value R/W
R: read the current counter value.
W: the counter is cleared.
0x0234
Di1 counter value R/W
R: read the current counter value.
W: the counter is cleared.
0x0238
Di2 counter value R/W
R: read the current counter value.
W: the counter is cleared.
