The application can disable event interrupts by writing in AC97 Controller Interrupt Disable Reg-
ister (AC97C_IDR). The AC97 Controller Interrupt Mask Register (AC97C_IMR) shows which
event can trigger an interrupt and which one cannot.
Endianness can be managed automatically for each channel, except for the Codec channel, by
writing to Channel Endianness Mode (CEM) in AC97C_CxMR. This enables transferring data on
AC-link in Big Endian format without any additional operation.
Word to be written in AC97 Controller Channel x Transmit Holding Register (AC97C_CxTHR)
(as it is stored in memory or microprocessor register).
Word stored in Channel x Transmit Holding Register (AC97C_CxTHR) (data to transmit)
Data transmitted on appropriate slot: data[19:0] = {Byte2[3:0], Byte1[7:0], Byte0[7:0]}.
Halfw ord to be written in AC97 Controlle r Channel x Transmit Holding Register
(AC97C_CxTHR).
Halfword stored in AC97 Controller Channel x Transmit Holding Register (AC97C_CxTHR) (data
to transmit).
Data emitted on related slot: data[19:0] = {0x0, Byte1[7:0], Byte0[7:0]}.
Halfw ord to be written in AC97 Controlle r Channel x Transmit Holding Register
(AC97C_CxTHR).
Halfword stored in AC97 Controller Channel x Transmit Holding Register (AC97C_CxTHR) (data
to transmit).
Data emitted on related slot: data[19:0] = {0x000, Byte1[1:0], Byte0[7:0]}.
