Functional Description
Clock Management
Interrupts
DMA
Equalization Filter
The Audio Bitstream DAC needs a separate clock for the D/A conversion operation. This clock
should be set up in the generic clock register in the power manager. The frequency of this clock
must be 256 times the frequency of the desired samplerate (f
clock must have a frequency of 12.288MHz.
The Audio Bitstream DAC interface has an interrupt line connected to the interrupt controller. In
order to handle interrupts, the interrupt controller must be programmed before configuring the
Audio Bitstream DAC.
All Audio Bitstream DAC interrupts can be enabled/disabled by writing to the Audio Bitstream
DAC Interrupt Enable/Disable Registers. Each pending and unmasked Audio Bitstream DAC
interrupt will assert the interrupt line. The Audio Bitstream DAC interrupt service routine can get
the interrupt source by reading the Interrupt Status Register.
The Audio Bitstream DAC is connected to the DMA controller. The DMA controller can be pro-
grammed to automatically transfer samples to the Audio Bitstream DAC Sample Data Register
(SDR) when the Audio Bitstream DAC is ready for new samples. This enables the Audio Bit-
stream DAC to operate without any CPU intervention such as polling the Interrupt Status
Register (ISR) or using interrupts. See the DMA controller documentation for details on how to
setup DMA transfers.
In order to use the Audio Bitstream DAC the product dependencies given in
page 722
and I/O lines in order to ensure correct operation of the Audio Bitstream DAC.
The Audio Bitstream DAC is enabled by writing the ENABLE bit in the Audio Bitstream DAC
Control Register (CR). The two 16-bit sample values for channel 0 and 1 can then be written to
the least and most significant halfword of the Sample Data Register (SDR), respectively. The
TX_READY bit in the Interrupt Status Register (ISR) will be set whenever the DAC is ready to
receive a new sample. A new sample value should be written to SDR before 256 DAC clock
cycles, or an underrun will occur, as indicated by the UNDERRUN status flags in ISR. ISR is
cleared when read, or when writing one to the corresponding bits in the Interrupt Clear Register
(ICR).
For interrupt-based operation, the relevant interrupts must be enabled by writing one to the cor-
responding bits in the Interrupt Enable Register (IER). Interrupts can be disabled by the Interrupt
Disable Register (IDR), and active interrupts are indicated in the read-only Interrupt Mask Regis-
ter (IMR).
The Audio Bitstream DAC can also be configured for peripheral DMA access, in which case only
the enable bit in the control register needs to be set in the Audio Bitstream DAC module.
The equalization filter is a simple 3-tap FIR filter. The purpose of this filter is to compensate for
the pass band frequency response of the sinc interpolation filter. The equalization filter makes
the pass band response more flat and moves the -3dB corner a little higher.
