and the external circuitry connected to TX1 and TX2.
[5] During operation with a typical circuitry the overall current is below 100 mA.
10.1.2 Voltage regulator characteristics
[1] The internal regulator is only enabled when the USB interface is selected by I0 and I1.
10.2 Antenna presence self test thresholds
The values in Table 9 are guaranteed by design. Only functional is done in production for
cases andet_ithl[1:0] = 10b and for andet_ithh[2:0] = 011b.
