Functional Description
At this point, control has been passed to system software via the interrupt. Software
should:
40.5.1.5.2 Charging Host Port
For a charging host port, the module does the following:
At this point, control has been passed to system software via the interrupt. Software
should:
1010
1. Read the STATUS register.
2. Disable the USB controller to prevent transitions on the USB D+ or D- lines from
3. Set the CONTROL[IACK] bit to acknowledge the interrupt.
4. Set the CONTROL[SR] bit to issue a software reset to the module.
5. Disable the module.
6. Communicate the appropriate charge rate to the external battery charger IC; see
1. Read the STATUS register.
2. Set the CONTROL[IACK] bit to acknowledge the interrupt.
3. Set the CONTROL[SR] bit to issue a software reset to the module.
4. Disable the module.
5. Communicate the appropriate charge rate to the external battery charger IC; see
• Updates the STATUS register to reflect that a dedicated charger has been detected
• Sets the CONTROL[IF] bit.
• Generates an interrupt if enabled (the CONTROL[IE] bit is set).
• Updates the STATUS register to reflect that a charging host port has been detected
• Sets the CONTROL[IF] bit.
• Generates an interrupt if enabled (the CONTROL[IE] bit is set).
