Low Voltage Reset
LVR
The microcontroller provides low voltage reset circuit in
order to monitor the supply voltage of the device. If the
supply voltage of the device is within the range
0.9V~V
LVR
such as changing a battery, the LVR will au-
tomatically reset the device internally.
The LVR includes the following specifications:
The low voltage (0.9V~V
LVR
) has to remain in their
original state to exceed 1ms. If the low voltage state
does not exceed 1ms, the LVR will ignore it and do not
perform a reset function.
The LVR uses the OR function with the external
RES signal to perform chip reset.

Low Voltage Reset
Note:
*1: To make sure that the system oscillator has stabilized, the SST provides an extra delay of 1024 system
clock pulses before entering the normal operation.

Mouse Hardware Wake-Up Function
When the HT82K96E is used for USB mouse application, in order to decrease the power consumption of the
HT82K96E in suspend mode. The HT82K96E has built-in Mouse Hardware wake-up function. Once the HT82K96E
jump to suspend mode, and the HWKUPSB (bit7 of SCC) is set to 1. The HT82K96E will automatically switch the IRPT
control pin (PC0) and detect movement of the X1, X2, Y1, Y2, Z1, Z2, corresponding to (PA0~PA5) and the state of the
five button corresponding to PA6, PA7, PB6, PB7, and PD4. Once there are mouse movement or state change. The
HT82K96E will wake-up the MCU by I/O method, otherwise the MCU is in suspend mode.
How long the HT82K96E to turn on the IRPT, and the low pulse period of the PC0 is defined by bit0~3 of the WDTS
(wake-up period) and the bit0~bit2 of the SCC (LED_on period) respectively. The following diagram show the IRPT
control pin timing.
