11.4.3.5

Power Management Interrupt Status Register (PM_IRQ_STAT)

This register reflects the status of various PM_IRQ_STAT sources. Whether an interrupt is generated or not depends

on the values in the Power Management Interrupt Enable and Control Register (PM_IRQ_EN).

Bits in this register are set by hardware and must be cleared by software.

11.4.3.6

RX SOP Interrupt Status Register (RX_SOP_IRQ_STAT)

This register reflects the status of the occurrence of various received SOP types. The SOP type does not need to be

enabled via the RX Control Register B (RX_CTL_B) in order for a status bit to be set. Whether an interrupt is generated

or not depends on the value of the RX SOP Interrupt Enable Register (RX_SOP_IRQ_EN).

The bits in this register are not cascaded into the RX Interrupt Status Register but instead are enabled and OR'ed into

their own interrupt signal output.

Bits in this register are set by hardware and must be cleared by software.

UPD_ACT_WS

USB PD activity detected. Set asynchronously by assertion of the receive

input signal at the beginning of any activity.

To prevent metastability this interrupt should only be enabled when software

plans to stop the clocks.

Clearing the USB_PD_ACT_WS_EN bit will actually prevent this bit from

being set unlike the other interrupt status bits.

This bit is not affected by either UPD_CLK_STOP_EN or UPD_WU_EN.

USB PD Activity status is available in other register bits during normal opera-

tion.
