Hi,
I set RESET_REQ bit of RSTCR register in LS1046A to 1,why the pin RESET_REQ_B can not output reset request? Whether I set RESET_REQ bit to 1 or 0, RESET_REQ_B always output level 0.
Best Regards

Low state of RESET_REQ_B signal means that reset request is already issued.
Did you check this signals after reset? Is it high when device comes out of reset sequence?

Thanks,Bulate.
After reset,RESET_REQ_B constantly keep low. This signal is only pulled high by pull up resistor during reset.
So if I use the low RESET_REQ_B to trig a PORESET_B to LS1046A,the LS1046A would not run up and keep in reset state.
I've checked the LS1046A Reference Manual.It refers to that RESET_REQ_B is Negated-Indicates no reset request in table 4-3. Does it mean that RESET_REQ_B low issuses no reset request and high issuses reset request?
Best regards.
