(13) D+ Pull-up control
Immediately after the power is switched on, the device may not be able to receive the token sent from the host
because the preparations at the firmware level have not been completed. In this case, until the initialization at the
firmware level is completed, the D+ line of the USB connector (the D- line in the case of a low speed device) is
turned off, and the 1.5k pull-up resistor is turned on after the initialization has been completed. To do this, a switch
circuit that can be turned on or off by the local MCU is provided in series with the 1.5K resistor.
In the ML60852, although it is possible to provide such switch circuits externally, it is also possible to use the
internal switch circuit in the ADSEL=0 state as shown in the following figure. The internal switch can be switched
on or off uniquely by the value of the bit D3 of the SYSCON register.
