Enable 125k pullup on USB_DP and 375k on USB_DN to provide USB_CHARGER functionality for USB1.
This functionality is a new USB spec and should not be enabled unless recommended by Freescale.
Enable 125k pullup on USB_DP and 375k on USB_DN to provide USB_CHARGER functionality for USB0.
This functionality is a new USB spec and should not be enabled unless recommended by Freescale.
Current threshold at which the Li-Ion battery charger signals to stop charging. The current represented by
each bit is as follows: (100 mA, 50 mA, 20 mA, 10 mA) = (bit 3, bit 2, bit 1, bit 0) It is recommended to set
this value to 10% of the charge current.
Reserved.
Magnitude of the battery charge current, the current represented by each bit is as follows: (400 mA, 200
mA, 100 mA, 50 mA, 20 mA, 10 mA) = (bit 5,bit 4, bit 3, bit 2, bit 1, bit 0)
Two's complement number that can be used to adjust the duty cycle of VDDD. This is intended for test
purposes only
