This bit controls the output of the remote wakeup signal (K state output).
This bit is valid only when the device state is “suspend” (DVSQ bits = “1xx”). The writing of “1” to this bit is
ignored when the device state is not suspend.
When “1” is written to this bit, the K state is output for 10 ms. The bit is automatically cleared to “0” after K
state output.
The bus idle state continues (this WKUP bit = “1”) for 2 ms after the Suspend state is detected when “1” is
written to this bit before outputting the K state for 10 ms.
The 2 ms and 10 ms time intervals are counted using a clock. Make sure that the counting stops if the clock is
not supplied (Note).
