Data Sheet
USB Audio Controller
SN11220ACF
means that the interval of USB HID Report IN is 10ms and this is default value.
Bit 13 to 15 are reserved for future using and influence no function of SN11220ACF.
Bit 12 is used to enable the EEPROM setting for configure the source of CODEC. If
bit 12 is “0”, PCM configuration is defined by pin PADFUN3~0.
PCM configuration bit = 1’b1
PCM configuration bit = 1’b0
Defined by PCM setting3~0
Defined by pin (PADFUN3~0)
Bit 11 to 8 is the configuration of CODEC if Bit 12 is set to 1.
