17.5 POWER PATH MANAGEMENT INTERRUPTS
w
Table 55 Configuring the USB Power Operation
The Power Path Management circuit is associated with three Interrupt event flags.
The PPM_SYSLO_EINT interrupt bit is set when the internal signal SYSLO
indicates a SYSVDD undervoltage condition, described in Section 24.4.
The PPM_PWR_SRC_EINT interrupt bit is set whenever the status of the Wall or USB supplies
changes, indicating a connection, disconnection, or a voltage. See Section 17.1.
The PPM_USB_CURR_EINT interrupt bit is set whenever the permitted USB current limit has been
reached. See Section 17.4.
Each of these secondary interrupts triggers a primary Power Path Management Interrupt, PPM_INT
(see Section 23). This can be masked by setting the mask bit(s) as described in Table 56.
