Functional Description
(Continued)
Format 2: Format 2 is the IDL, in which the 2B
a
D data
transfer is assigned to the first 19 bits of the
frame on the Bx and Br pins. Channels are as-
signed as follows: B1 (8 bits), D (1 bit), 1 bit ig-
nored, B2 (8 bits), D (1 bit), with the remaining
bits ignored until the next frame sync pulse. Fig-
ure 3-2 shows this format in DSI Slave Mode, and
Figure 3-5 shows DSI Master Mode.
Format 3: This format provides time-slot assignment capa-
bility for the B1 and B2 channels, which can be
independently assigned to any 8-bit wide time-
slot from 64 (or less) on the Bx and Br pins; the
Transmit and Receive directions are also inde-
pendently assignable. Also the D channel can be
assigned to any 2-bit wide time-slot from 256 (or
less) on the Bx and Br pins (D port disabled) or
on the Dx and Dr pins (see D-Channel Port sec-
tion). Figure 3-3 shows this format in DSI Slave
Mode, and Figure 3-6 shows DSI Master Mode;
see also Section 6.2.
Format 4: This is similar to the GCI format for the 2B
a
D
channels, but excludes the Monitor channel and
C/I channel. Channels are assigned to the first
26 bits of each frame as follows: B1 (8 bits), B2
(8 bits), ignored (8 bits), D (2 bits). The remaining
bits in the frame are ignored until the next frame
sync pulse. The relationship between BCLK and
data is the same as in the GCI mode for GCI
Channel 0, see Figure 7 (in DSI Master Mode,
BCLK

512 kHz and FS

put).
TL/H/9151–5
FSa defines B1 channel for Tx.
FSb defines B1 channel for Rx.

TL/H/9151–6
Delayed timing mode must be selected;
Time-slot immediate mode only (no TSA).
