DPPULLEN — D+ Pullup Enable
PTE3P — Pin PTE3 Pullup Enable
PTE2P — Pin PTE2 Pullup Enable
13.7.3 Pullup Control Register (PULLCR)
The pullup control register enables the embedded pullup resistor associated with port B [7:0].
PULL[7:0]EN — Pullup Enable Bit
Freescale Semiconductor
This read/write bit enables the USB D+ pullup option to VREF33 for pin PTE2.
This read/write bit enables the pullup option for pin PTE3 if it is not configured as an USB D– pin or
USB module is disabled.
This read/write bit enables the pullup option for pin PTE2 if it is not configured as an USB D+ pin or
USB module is disabled.
These read/write bits enables the embedded pullup resistor associated with the corresponding port
pin. Reset clears this bit.
1 = Configure PTE2 to have internal USB pullups to VREF33
0 = Disconnect PTE2 internal pullups
1 = Configure PTE3 to have 5k internal pullups
0 = Disconnect PTE3 internal pullups
1 = Configure PTE2 to have 5k internal pullups
0 = Disconnect PTE2 internal pullups
1 = Pullup resistor is enabled
0 = Pullup resistor is disabled
Address:
When the USB module is enabled, the pullup controlled by PTE2P and
PTE3P are disconnected; PTE2/D+ pin functions as D+ which has a
programmable pull-up resistor by setting the DPPULLEN bit.
