In suspended state, the device will consume considerably less power by turning off
the internal 48 MHz clock, PLL and crystal, and setting the internal regulator to
power-down mode. The ISP1161A suspend and resume clock scheme is shown in
Figure 37
.
Remark:
The ISP1161A can only be put into a fully suspended state only after both
the HC and the DC go into suspend state. At this point, the crystal can be turned off
and the internal regulator can be put into power-down mode.
Pin H_SUSPEND is the sensing output pin for HC’s suspended state. When the HC
goes into USBSuspend state, this pin will output a HIGH level (logic 1). This pin is
cleared to LOW (logic 0) level only when the HC is put into a USBReset state or
USBOperational state (refer to the HcControl register bits 7 to 6, 01H - read, 81H -
write). Bit 11, SuspendClkNotStop, of the HcHardwareConfiguration register (20H -
read, A0H - write), defines if the HC internal clock is stopped or kept running when
the HC goes into USBSuspend state. After the HC enters the USBSuspend state for
1.3 ms, the internal clock will be stopped if bit SuspendClkNotStop is logic 0.
9.9.2
HC wake-up from suspended state
There are three methods to wake up the HC from the USBSuspend state: hardware
wake-up, software wake-up, and USB bus resume.
They are described as follows:
Wake-up by pin H_WAKEUP
Pins H_SUSPEND and H_WAKEUP provide a method of remote wake-up control
for the HC without the need to access the HC internal registers. H_WAKEUP is an
external wake-up control input pin for the HC. After the HC goes into USBSuspend
state, it can be woken up by sending a HIGH level pulse to pin H_WAKEUP. This
will turn on the HC’s internal clock, and set bit 6, ClkReady, of the Hc
μ
PInterrupt
register (24H - read, A4H - write).
