Bus Timing Diagrams
The bus timings are designed to
be simple and to minimize the
effects of timing skew. This sec-
tion discusses some key points
with regard to bus timings and
illustrates typical STC transac-
tions with the use of waveforms.
Bus Timing Notes
1. Data is transferred in Little
Endian order, that is, the LSB
on the first byte is transmitted
first and the MSB of the second
or third byte is transmitted last.
2. There are no gaps between bytes
in the command or response
phases.
3. Each byte in the command and
response phase is preceded by a
start bit on the SCLK line.
4. For data sampling and clocking,
4.1.Input data is sampled on
the rising edge of SCLK.
4.2.Output data from the con-
troller is clocked out on the
falling edge of SCLK.
4.3.Output data from the slave
is clocked out on the rising
edge of SCLK.
5. The first low-to-high transition
of SCLK indicates that an STC
transition is pending. On re-
ceipt of his rising edge, the slave
will disable the LED. The next
SCLK low-to-high transition
indicates the start cycle, fol-
lowed by the command phase
(which the controller puts out
on the SWDAT line). The LED
needs to be disabled since TXD
and SWDAT are multiplexed. If
the LED is not disabled, then
the LED will pulse according to
the SWDAT bit stream.
6. The LED is re-enabled (by the
slave) on the last SCLK of the
STC transaction bit stream.
Normal infrared transmission
can resume. No SCLK transi-
tions should take place until the
next STC transaction else the
LED will be disabled.
7. The response from the slave is
carried on the SRDAT line,
which is multiplexed with RXD.
The detector is (internally) dis-
abled by the slave during the
response phase. This is to pre-
vent stray IR transitions from
corrupting the SRDAT bit
stream.
8. During a READ transaction, the
controller holds the SWDAT line
low for 1 clock after sending the
ADDRESS and INDEX byte. It
then holds it high and low for 3
clocks before the end of the
transaction. This is to allow the
transceiver to monitor the im-
pending end of a transaction
rather than by counting pulses.
9. When powered up, the trans-
ceiver is not ready to perform IR
transmissions. The controller
has to initialize the transceiver.
The brief powered up sequences
are:
9.1.On power up, an inter-
nally generated signal in the
transceiver sets the 3 con-
trol registers:
a) Control Register 0:
Bit 0: shutdown mode
Bit 1: RXD disabled
Bit 2: LED disabled
b) Control Register 1:
Bit 0-7: SIR mode
c) Control Register 2:
Bit 0-7: Power at 100%
level
9.2.The controller has to initial-
ize the transceiver by:
a) Hold SWDAT low
b) Toggle SCLK for at least
30 cycles
The transceiver is in STC mode
and ready to accept STC
transactions.
