Reset FIFO results
This command resets the 8 last cycle’s results available in the FIFO.
Master
Slave
— Activate the “Reset FIFO results” command:
Write at the address 00(h), the value 0080(h)
Byte 0 = 80(h) (Bit 7 = 1)
Byte 1 = 00(h)
Acknowledgement
Command echo:
— Byte 0 = 80(h) (Bit 7 = 1)
— Byte 1 = 00(h)
Command error code:
— Byte 2 = FF(h)
— Byte 3 = FF(h)
(if command error code = FFFF(h), command is in
progress)
Running “Reset FIFO results” command
Command finished
Command echo:
— Byte 0 = 80(h) (Bit 7 = 1)
— Byte 1 = 00(h)
Command error code if the command is correctly
carried out:
— Byte 2 = 00(h)
— Byte 3 = 00(h)
OR if an error occurred during the command:
— Byte 2 = 80(h) (Bit 7 = 1)
— Byte 3 = 00(h)
— Wait the end of the command:
command echo = 0080(h)
command error code ≠ FFFF(h) (end of command)
— Deactivate the “Reset FIFO results” command:
Write at the address 00(h) the value 0000(h)
Byte 0 = 00(h) (Bit 7 = 0)
Byte 1 = 00(h)
The master instrument must always set to zero the command bit. If it is not done, the slave instrument
will not detect the following command on this bit. It has detection on the rising edge (when the bit
state goes from 0 to 1).
