1.5.10
The ATA block is an AT attachment host interface. Its main use is to interface with IDE hard disc drives
and ATAPI optical disc drives. It interfaces with the ATA device over a number of ATA signals. The ATA
interface is compliant to the ATA-6 standard, and supports PIO mode 0 to 4, multiword DMA mode 0, 1
and 2, and ultra DMA mode 0 to 3.
1.5.11
The two FlexCan modules are full implementation of the Bosch CAN protocol specification 2.0B, which
supports both standard and extended message frames. The 32 message buffers that are supported, are
stored in an embedded RAM.
1.5.12
There is an on-chip real-time clock. The real-time clock needs an external 32.768 kHz crystal, and an
external keep-alive battery. The real-time clock has an anti-tamper feature that will detect when the battery
is removed.
1.5.13
The MCF5253 digital audio interface provides three serial Philips IIS/Sony EIAJ interfaces. One interface
is a 4-pin (1 bit clock, 1 word clock, 1 data in, 1 data out), the other two interfaces are 3-pin (1 bit clock,
1 word clock, 1 data in or 1 data out). The serial interfaces have no limit on minimum sampling frequency.
Maximum sampling frequency is determined by the maximum frequency on the bit clock input. (1/3 the
frequency of the internal system clock.)
1.5.14
The MCF5253 has two digital audio input interfaces, and one digital audio output interface. There are four
digital audio input pins and two digital audio output pins. An internal multiplexer selects one of the four
inputs to one of the two digital audio inputs.
One digital audio output carries the consumer “c” channel, the other carries the professional “c” channel.
The IEC958 outputs can take the output from the internal IEC958 generator, or multiplex out one of the
four IEC958 inputs.
1.5.15
The audio interfaces connect to an internal bus that carries all audio data. Each receiver places its received
data on the audio bus and each transmitter takes data from the audio bus for transmission. Each transmitter
has a source select register.
In addition to the audio interfaces, there are six CPU accessible registers connected to the audio bus. Three
of these registers allow data reads from the audio bus and allow selection of the audio source. The other
