PA7 - 0, PB7 - 0, PC7 – 0 and PD7 - 0
Each of these bits transmits the state of a port. The data from the OUTPUT PORTs are transmitted
(feedback) to the bits that are configured as OUTPUT PORTs. However, if bits PD7 – 4 are configured as
FLAG OUTPUT, ”1” is transmitted to the corresponding bit. Additionally, if the transmit trigger is configured
as the external trigger, ”0” is transmitted to either PC0 or PD0 pin that corresponds to the trigger input pin,
nPISTR1 or nPISTR 2 respectively.
PGS2 - 0

OPICDONE
After receiving the START TRANSMIT command, TMC2084 commences the transmission of the above
data: configuration data (3 bits), status data (9 bits) input data (32 bits) and NST(16 bits).
For detail information on each status bit, see the section 2.8 Status Bits.
NST15 - 0 (Time stamp)
TMC2084 sends the INPUT DATA packet with time information (NST value) attached. When the transmit
trigger is configured as the external trigger mode that uses NST latch, the NST value taken at the time the
input data is latched is transmitted. In the external trigger mode that does not use the NST latch, the
preceding NST value is transmitted regardless of the input data latch (For detail information on the transmit
trigger, see the section on Configuration Through the Network).
