PSoC5LP : Timing of the DMA trq terminal

MiNe_85951 · ‎Jun 28, 2020

Hi,

We are considering DMA for PSoC5LP.

We would like to confirm at what timing the positive edge of tqp trq becomes valid.

Could you tell us the detailed timing when the positive edge of trq becomes effective?

The data sheet of DMA componet does not include detailed timings.

Regards,

A short positive impulse trq will allow you to interrupt the transmission if it is already active but for too long long and should be interrupted.

The nrq signal will be generated immediately after trq.

Perhaps this is useful for hardware control, but I could not find a use for this. My comments and link to an my example.
