ADVANCE PRODUCT INFORMATION - JUL 26, 2011
The transition times can be set for two different slope modes using register CH CFG. The transmitter is
operable only if VDD, L+ and chip temperature are within their specified limits. Otherwise the transmitter
is disabled.

6.3.1.1
Transmitter Overload
In case of high power dissipation (e.g. due to short circuit of the driver) the chip temperature will
increase. To protect the device, an internal over temperature sensor for each driver is implemented. In
case of over temperature, the affected driver is disabled. The other output driver can operate
independently.
The transmitters are switched on after a the over temperature condition disappeared. The over
temperature flag is set in CH STAT, to generate an interrupt use bit OTIE in TRX CFG
