  • Method and apparatus for facilitating AC-link communications between a controller and a slow peripheral of a codec
    Patent number: 6434633
    Abstract: A method and apparatus for facilitating AC-link communications between a controller and a slow peripheral of a codec is disclosed. In one embodiment, the GPIO_INT bit (i.e. bit 0 in slot 12 in the AC-link's SDATA_IN line) is utilized as an interrupt flag to indicate when data requested by the controller from the slow peripheral is returned and is available to be read by the controller. The GPIO_INT bit can also be used to indicate when a write into the slow peripheral is completed. In this embodiment, a “peripheral ready bit” or a “peripheral ready signal” originated from the slow peripheral is used to set the GPIO_INT bit. Another embodiment is directed to controllers which ignore the GPIO_INT bit as a source of interrupt. To accommodate these controllers, one of the GPIO bits is used to send the value of the “peripheral ready bit” to the controller.
