The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
Before using the AC97 Controller receiver, the PIO controller must be configured in order for the
AC97C receiver I/O lines to be in AC97 Controller peripheral mode.
Before using the AC97 Controller transmitter, the PIO controller must be configured in order for
the AC97C transmitter I/O lines to be in AC97 Controller peripheral mode.
The AC97 clock is generated by the power manager. Before using the AC97, the programmer
must ensure that the AC’97 clock is enabled in the power manager.
In the AC97 description, Master Clock (MCK) is the clock of the peripheral bus to which the
AC97 is connected. It is important that that the MCK clock frequency is higher than the SCLK
(Bit Clock) clock frequancy as signals that cross the two clock domains are re-synchronized.
The AC97 interface has an interrupt line connected to the interrupt controller. In order to handle
interrupts, the interrupt controller must be programmed before configuring the AC97.
All AC97 Controller interrupts can be enabled/disabled by writing to the AC97 Controller Inter-
rupt Enable/Disable Registers. Each pending and unmasked AC97 Controller interrupt will
assert the interrupt line. The AC97 Controller interrupt service routine can get the interrupt
source in two steps:
•Reading and ANDing AC97 Controller Interrupt Mask Register (IMR) and AC97 Controller
•Reading AC97 Controller Channel x Status Register (CxSR).)
Status Register (SR).
