5:
This is the module differential current when the USB module is enabled and clocked at 48 MHz, but with no USB cable
attached. When the USB cable is attached, or data is being transmitted, the current consumption may be much higher (see
attached. When the USB cable is attached, or data is being transmitted, the current consumption may be much higher (see
). During USB Suspend mode (USBEN = 1, SUSPND = 1, bus
in Idle state), the USB module current will be dominated by the D+ or D- pull-up resistor. The integrated pull-up resistors use
“resistor switching” according to the resistor_ecn supplement to the “USB 2.0 Specification” and therefore, may be as low as
900Ω during Idle conditions.
