The
USB Power Management Register
, shown in
Figure 1.54, is used for power management in the
USB FCU.
USB Suspend Detection Flag (SUSPEND)
When the USB FCU does not detect any bus activ-
ity on D+/D- for at least 3ms, it sets the Suspend
Detection Flag (SUSPEND) and generates an inter-
rupt. This bit is cleared when signaling (from the
host) is detected on D+/D- [which sets the Resume
Detection Flag (RESUME) and generates an inter-
rupt] or the Remote Wake-up Bit (WAKEUP) is set
and then cleared by the CPU. If the USB clock was
disabled during the suspend state, the SUSPEND
bit is not cleared until after the USB clock is re-en-
abled.
USB Resume Detection Flag (RESUME)
When the USB FCU is in the suspend state and de-
tects signaling on D+/D- (from the host), it sets the
Resume Detection Flag (RESUME) and generates
an interrupt. The CPU writes a “1” to INST14 (bit 6
of USB Interrupt Status Register 2) to clear this
flag.
USB Remote Wake-up Bit (WAKEUP)
The CPU writes a “1” to the WAKEUP bit for remote
wake-up. While this bit is set, and the USB FCU is
in suspend mode, it will generate resume signaling
to the host. The CPU must keep this bit set for a
minimum of 10ms and a maximum of 15ms before
writing a “0” to this bit.

SUSPEND
USB Suspend Detection Flag (bit 0) (Read only)
0: No USB suspend detected
1: Idle state for greater than 3ms (USB suspend) detected
USB Resume Detection Flag (bit 1)(Read only)
0: No USB resume signaling detected
1: USB resume signaling detected
USB Remote Wake-up Bit (bit 2)
0: End remote resume signaling
1: Send remote resume signaling (only if SUSPEND = “1”)
