18.3.18
SLOT STATUS BITS
The SLOT<3:0> status bits in the DCISTAT SFR indi-
cate the current active time slot. These bits correspond
to the value of the Frame Sync generator counter. The
user may poll these status bits in software when a DCI
interrupt occurs to determine what time slot data was
last received and which time slot data should be loaded
into the TXBUF registers.
18.3.19
CSDO MODE BIT
The CSDOM control bit controls the behavior of the
CSDO pin during unused transmit slots. A given trans-
mit time slot is unused if it’s corresponding TSEx bit in
the TSCON SFR is cleared.
If the CSDOM bit is cleared (default), the CSDO pin is
low during unused time slot periods. This mode is used
when there are only two devices attached to the serial
bus.
If the CSDOM bit is set, the CSDO pin is tri-stated dur-
ing unused time slot periods. This mode allows multiple
devices to share the same CSDO line in a multichannel
application. Each device on the CSDO line is config-
ured so that it only transmits data during specific time
slots. No two devices transmit data during the same
time slot.
18.3.20
DIGITAL LOOPBACK MODE
Digital Loopback mode is enabled by setting the
DLOOP control bit in the DCICON1 SFR. When the
DLOOP bit is set, the module internally connects the
CSDO signal to CSDI. The actual data input on the
CSDI I/O pin is ignored in Digital Loopback mode.
18.3.21
UNDERFLOW MODE CONTROL BIT
When an underflow occurs, one of two actions may
occur depending on the state of the Underflow mode
(UNFM) control bit in the DCICON1 SFR. If the UNFM
bit is cleared (default), the module transmits ‘0’s on the
CSDO pin during the active time slot for the buffer loca-
tion. In this operating mode, the Codec device attached
to the DCI module is simply fed digital ‘silence’. If the
UNFM control bit is set, the module transmits the last
data written to the buffer location. This operating mode
permits the user to send continuous data to the Codec
device without consuming CPU overhead.
18.4
DCI Module Interrupts
The frequency of DCI module interrupts is dependent
on the BLEN<1:0> control bits in the DCICON2 SFR.
An interrupt to the CPU is generated each time the set
buffer length has been reached and a shadow register
transfer takes place. A shadow register transfer is
defined as the time when the previously written TXBUF
values are transferred to the transmit shadow registers
and new received values in the receive shadow
registers are transferred into the RXBUF registers.
18.5
DCI Module Operation During CPU
Sleep and Idle Modes
18.5.1
DCI MODULE OPERATION DURING
CPU SLEEP MODE
The DCI module has the ability to operate while in
Sleep mode and wake the CPU when the CSCK signal
is supplied by an external device (CSCKD = 1). The
DCI module generates an asynchronous interrupt
when a DCI buffer transfer has completed and the CPU
is in Sleep mode.
18.5.2
DCI MODULE OPERATION DURING
CPU IDLE MODE
If the DCISIDL control bit is cleared (default), the mod-
ule continues to operate normally even in Idle mode. If
the DCISIDL bit is set, the module halts when Idle
mode is asserted.
18.6
AC-Link Mode Operation
The AC-Link protocol is a 256-bit frame with one 16-bit
data slot, followed by twelve 20-bit data slots. The DCI
module has two operating modes for the AC-Link pro-
tocol. These operating modes are selected by the
COFSM<1:0> control bits in the DCICON1 SFR. The
first AC-Link mode is called ‘16-bit AC-Link mode’ and
is selected by setting COFSM<1:0> = 10. The second
AC-Link mode is called ‘20-bit AC-Link mode’ and is
selected by setting COFSM<1:0> = 11.
18.6.1
16-BIT AC-LINK MODE
In the 16-bit AC-Link mode, data word lengths are
restricted to 16 bits. Note that this restriction only
affects the 20-bit data time slots of the AC-Link proto-
col. For received time slots, the incoming data is simply
truncated to 16 bits. For outgoing time slots, the 4 LSbs
of the data word are set to ‘0’ by the module. This trun-
cation of the time slots limits the A/D and DAC data to
16 bits but permits proper data alignment in the TXBUF
and RXBUF registers. Each RXBUF and TXBUF
register contains one data time slot value.
