Invalid Commands Handling
There are some commands and register addresses, which cannot be decoded by the SITC. The slave ignores such invalid data for the
internal logic. Below the different types and the slave reaction to them are shown.
Description
Master Command
Invalid command in read mode
Index [3:0] & C = 0
Invalid command in write mode
Index [3:0] & C = 1
No reaction means that the slave does not start the respond phase.
Reset
There is no external reset pin at Vishay IrDA trans-
ceivers. In case of transition error there are two ways
to set the SITC in a defined state: The first one is
power off. The second one is that the transceiver
monitors the IRTX/SWDAT line in any state. If this line
is assumed low for
≥
30 clock cycles then the trans-
ceiver must be set to the command start state and set
all registers to default implemented values.
