SOFTWARE RESET FOR LS1046

Ellu24 — Thu, 09 Jun 2022 07:31:43 GMT

I am designing a hardware using LS1046. For our application, there is no need of reset button or hardware reset and planning to do software reset. Then how should I connect the reset pins of LS1046 and peripherals.

Thanks in advance

Please refer to the update from the AE team.

Software reset is implemented using RESET_REQ_B signal. Customer needs to take care that RESET_REQ_B signal pulse width is small hence customer needs to take care in hardware so that reset is low for required time.

Customer can refer LS1046ARDB design (available on web).

Please provide me details about which signal connectivity customer is not clear.

Thanks for the reply. Some of my questions while doing software reset are:

1) Can I use the attached circuit for providing power on reset for LS1046 (CPU) and other peripherals?( In my application, I am not using reset switch) . I referred FRWY LS 1046 reference design. Please find the attachment.

2) What should I do to implement HRESET?

Thanks in advance
