Description

interval

UINT

Time pulse frequency; unit: μs; supports: 1000000, 500000, 200000, 100000

length

UINT

Time pulse width; unit: μs; recommended: 25%*interval ≤ length ≤ 75%*interval (High-level when the rising edge is aligned to top of second; low-level when the falling edge is aligned to top of second)

flag

UINT

Time pulse configuration: Bit 0 0 - Disable time pulse output 1 - Enable time pulse output Bit 1 0 - Rising edge at top of second 1 - Falling edge at top of second Bit 2 0 - Output when positioning 1 - Output when switching on the receiver

antDelay

INT

Antenna delay; unit: ns; range: -32768 to 32767

rfDelay

INT

RF delay; unit: ns; range: -32768 to 32767

usrDelay

INT

User-set delay; unit: ns; range: -32768 to 32767; modifying the delay may result in a loss of precision when time pulse is adapting to the value
