18.6.2
The 20-bit AC-Link mode allows all bits in the data time
slots to be transmitted and received but does not main-
tain data alignment in the TXBUF and RXBUF
registers.
The 20-bit AC-Link mode functions similar to the Multi-
channel mode of the DCI module, except for the duty
cycle of the Frame Synchronization signal. The AC-
Link Frame Synchronization signal should remain high
for 16 CSCK cycles and should be low for the following
240 cycles.
The 20-bit mode treats each 256-bit AC-Link frame as
sixteen, 16-bit time slots. In the 20-bit AC-Link mode,
the module operates as if COFSG<3:0> = 1111 and
WS<3:0> = 1111. The data alignment for 20-bit data
slots is ignored. For example, an entire AC-Link data
frame can be transmitted and received in a packed
fashion by setting all bits in the TSCON and RSCON
SFRs. Since the total available buffer length is 64 bits,
it would take 4 consecutive interrupts to transfer the
AC-Link frame. The application software must keep
track of the current AC-Link frame segment.
18.7
The DCI module is configured for I
a value of ‘01’ to the COFSM<1:0> control bits in the
DCICON1 SFR. When operating in the I
DCI module generates Frame Synchronization signals
with a 50% duty cycle. Each edge of the Frame
Synchronization signal marks the boundary of a new
data word transfer.
The user must also select the frame length and data
word size using the COFSG and WS control bits in the
DCICON2 SFR.
