TMS320F28388D: Length of first encoder clock in BISSC solution

The green signal looks like SPI clock to me. Can you confirm which signal is which? Is the response correct?

Hi Lori,

The green is encoder block. In one of customer's other projects then adapted BISSC to SSI where then use encoder block directly as SPI clock. In both projects, they observed this.

The response is correct. Just want to know where this comes from.

I recall there is a toggle on SPI clock when the CLB is reset. Looks like that is what is occurring here since SPI clock is being reused as encoder clock. 

The output xbar latch can be used to hold the signal when the CLB is reset. This is from the design guide Figure 2-10
