A flowchart for the write operation appears in
Figure 18
.
Note that if CCLK is slower than f
CCNH
, the FPGA never
asserts BUSY, In this case, the above handshake is unnec-
essary, and data can simply be entered into the FPGA every
CCLK cycle.
Abort
During a given assertion of CS, the user cannot switch from
a write to a read, or vice-versa. This action causes the cur-
rent packet command to be aborted. The device remains
BUSY until the aborted operation has completed. Following
an abort, data is assumed to be unaligned to word bound-
aries, and the FPGA requires a new synchronization word
prior to accepting any new packets.
To initiate an abort during a write operation, de-assert
WRITE. At the rising edge of CCLK, an abort is initiated, as
shown in
Figure 19
.
