177 / 221 page  2016-2017 Microchip Technology Inc. DS00002084C-page 177 UPD360 12.5.1 PPC VBUS CURRENT MEASUREMENT REGISTER (PPC_VBUS_CURRENT) This register stores the measured current value delivered to the external device via the VBUS pin. This value is updated continuously while the device is in the Active power state. The bit weights are in mA and the range is from 0mA to 3400mA (1 LSB = 13.3mA). This data will be cleared whenever the port power switch is turned off (or any time that VBUS is discharged). Note: This register’s data is not intended for use when current is <100mA. 12.5.2 PPC VBUS PORT STATUS REGISTER (PPC_VBUS_PORT_STS) Address: 0400h Size: 8 bits Bits Description Type Default 7 1706.2 mA RO 0b 6 853.1 mA RO 0b 5 426.6 mA RO 0b 4 213.3 mA RO 0b 3 106.6 mA RO 0b 2 53.3 mA RO 0b 1 26.7 mA RO 0b 0 13.3 mA RO 0b Address: 0402h Size: 8 bits Bits Description Type Default 7 RESERVED RO - 6 ALERT This bit is asserted when an error (ERR) occurs in the PPC. It also asserts the PPC_INT bit in the Interrupt Status Register (INT_STS), if enabled. This bit can also be configured to assert when the LOW_CUR (portable device is pulling less current and may be finished charging) bit is set and linked via the ALERT_LINK bit. The ALERT bit is de-asserted when all error conditions that may assert it (error condition, and LOW_CUR if linked) have been removed or reset as necessary. RO 0b 5 RESERVED RO - 4 CC_MODE Indicates that the IBUS current on VBUS has exceeded ILIM and sourcing Region 2. RO 0b 3:0 RESERVED RO - |
