4.39 Status Response

Status Response is the default response to the processor, and is defined as shown in table

Table 31. MISO Status Response Definition

Diagnostic fault indication flag indicates if a fault exists during the on-chip diagnostic. This bit reports the

fault status on channel/s enabled in the STATUS.FLT configuration register.

Diagnostic completion status flag indicates if the on-chip diagnostic is completed. This flag will be set when

all the requested channels finish the diagnostic sequence (see Figure 15). This flag does not include the

status of "short between loops" test.

ARMx status flag indicates the state of the respective ARMx signal, including the pulse stretch timer. If the

pulse stretch timer is initiated by a deployment command, it does not assert the ARMx status flag. This

flag is de/asserted as soon as the de-glitch timer is expired.

Deploy command success bit indicates if the corresponding channel has finished its deployment se-

quence. This bit is set when deployment period, 2ms or 4ms, has expired. Once this bit is set, it inhibits

the subsequent deployment command until OSD receives a SPI command to clear this deployment suc-

cess flag. Refer to Figure 9, Figure 10, Figure 11, and Figure 12 for the operation of deployment success

flag.
