(2) The UART switch path connects from the UART buffers to the port pins. See Section 7.19 for buffer specifications.
(3) See Section 7.16 for the USB_EP specifications.
7.13 Port Data Multiplexer Clamp Characteristics
Recommended operating conditions; T
A
= –10 to 85°C unless otherwise noted
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
VCLMP_IND Clamp voltage triggering indicator to digital core 3.8 3.95 4.1 V
ICLMP_IND Clamp current at VCLMP_IND 10 250 μA
TCLMP_PRT
(1)
Time from clamp current crossing ICLMP_IND to
interrupt signal assertion
I ≥ ICLMP_IND rising 0 4 μs
ICLMP USB_EP and USB_RP port clamp current
V = LDO_3V3 250 nA
V = VCLMP_IND + 500 mV 3.5 15 mA
(1) The TCLMP_PRT time includes the time through the digital synchronizers. When the clock speed is reduced, the signal assertion time
may be longer.
