ADSP 21364 -Miscellaneous interrupt.

Hi,

      1)   I am trying to use  MISCB3_I   interrupt ,i have done the SRU configuration for that but i dont understand how to write interrupt signal for that,as in the programmable interrupts there are P0I & P012I for DAI which one to be used for MISCB3_I or if not this way then how?

 

 

2)When will this kind of interrupt go into the ISR ,like when the signal on that particular pin becomes high or how ?

 

3)I want to interface ADIS163xx with ADSP213xx ,connect the reset pin of ADIS with ADSP,how do i do that do i need to do some sru/dai,one thing the reset pin of ADIS is not connected to any of flags of ADSP.

 

 

thanks

    Hi,

    Please see my reply below:

    >> Bit 25 of DAI_IRPTL_PRI register will decide whether the DAI high or low priority interrupt will be generated. If this bit is set, then P0I interrupt will be generated else P12I will be generated.

    2)When will this kind of interrupt go into the ISR ,like when the signal on that particular pin becomes high or how ?

    >> The interrupt will be generated on rising edge if  bit 25 of the DAI_IRPTL_RE is set or  on falling edge when bit 25 of DAI_IRPTL_FE is set or on both edges if bit 25 of both registers are set.

    3)I want to interface ADIS163xx with ADSP213xx ,connect the reset pin of ADIS with ADSP,how do i do that do i need to do some sru/dai,one thing the reset pin of ADIS is not connected to any of  flags of ADSP.

    >> RESET can't be mapped to any of the DAI pins. Its a dedicated pin on the processor.

    Hope this helps.

    Thanks,
