CC3200 SPI Chip Select - Need configurable delay

Ignisuti

Other Parts Discussed in Thread: CC3200

Hello,

We have a very custom application that requires us to set the delay between chip select assertion & de-assertion to 0 (or as low as possible). I know this is configurable with the Freescale/NXP Kinetis ARM family MCUs, but I don't see a register to configure this for the TI CC3200 ARM MCU.

Have I missed it? Is it possible that the register/configuration exists, but isn't documented?

You mean the delay from asserting CS to SPI clock, i.e tLead and tLag times below right?

Correct.

I know they were configurable on the Kinetis ARM Cortex M4 parts. So, I'm hoping there's some registers (even if undocumented) that will allow me to do this on the CC3200 ARM Cortex M4.

Anyone know if this is possible on the CC3200?

I do not yet have a definite answer. Checking with the SoC designers. It is available on our many other SoCs.
Sorry for the delay.,.,
