HT82M9BE/HT82M9BA
Rev. 1.80

December 22, 2008
There are some timing constrains and usages illustrated here. By setting the MISC register, the MCU can perform read-
ing, writing and clearing actions. There are some examples shown in the following table for endpoint FIFO reading, writ-
ing and clearing.
Actions
MISC Setting Flow and Status
Read FIFO0 sequence
00H
®01H®delay of 2ms, check 41H®read* from FIFO0 register
and check if not ready (01H)
®03H®02H
Write FIFO1 sequence
0AH
®0BH®delay of 2ms, check 4BH®write* to FIFO1 register and
check if not ready (0BH)
®09H®08H
Check whether FIFO0 can be read or not
00H
®01H®delay of 2ms, check 41H (if ready) or 01H (if not ready)
®00H
Check whether FIFO1 can be written to or not
0AH
®0BH®delay of 2ms, check 4BH (if ready) or 0BH (if not ready)
®0AH
Write 0-sized packet sequence to FIFO 0
02H
®03H®delay of 2ms, check 43H®01H®00H
Note: *: There are 2
ms gap existing between 2 reading actions or between 2 writing actions

USB Active Pipe Timing
The USB active pipe accessed by the host cannot be used by the MCU simultaneously. When the host finishes its work,
the signal, a USB_INT will be produced to tell the MCU that the pipe can be used and the acted pipe No. will be shown
in the signal, ACT_PIPE as well. The timing is illustrated in the figure below.

Suspend Wake-Up and Remote Wake-Up
If there is no signal on the USB bus for over 3ms, the
HT82M9BE/HT82M9BA will go into a suspend mode.
The Suspend line (bit 0 of the USC) will be set to 1 and a
USB interrupt is triggered to indicate that the
HT82M9BE/HT82M9BA should jump to the suspend
state to meet the 500
mA USB suspend current spec.
In order to meet the 500
mA suspend current, the pro-
grammer should disable the USB clock by clearing the
USBCKEN (bit3 of the SCC) to
²0². The suspend cur-
rent is 400
mA.
When the resume signal is sent out by the host, the
HT82M9BE/HT82M9BA will wake-up the MCU by USB
interrupt and the Resume line (bit 3 of the USC) is set. In
order to make the HT82M9BE/HT82M9BA function
properly, the programmer must set the USBCKEN (bit 3
of the SCC) to 1 and clear the SUSP2 (bit4 of the SCC).
Since the Resume signal will be cleared before the Idle
signal is sent out by the host and the Suspend line (bit 0
of the USC) is going to
²0². So when the MCU is detect-
ing the Suspend line (bit0 of the USC), the Resume line
should be remembered and taken into consideration.
After finishing the resume signal, the suspend line will
go inactive and a USB interrupt is triggered. The follow-
ing is the timing diagram:
The device with remote wake-up function can wake-up
the USB Host by sending a wake-up pulse through
RMWK (bit 1 of USC). Once the USB Host receive the
wake-up signal from the HT82M9BE/HT82M9BA, it will
