Preliminary
The PG0 is pin-shared with INT.
It is recommended that unused or not bonded out I/O
lines should be set as output pins by software instruction
to avoid consuming power under input floating state.
Low Voltage Reset
- LVR
The HT48E30 provides a low voltage reset circuit in or-
der to monitor the supply voltage of the device. If the
supply voltage is within the range 0.9V~VLVR, such as
while changing a battery, the LVR will automatically re-
set the device internally.
The LVR includes the following specifications:
Within the low voltage range (0.9V~V
LVR), the device
remains in their original state until exceeding 1ms. If
the low voltage state does not exceed 1ms, the LVR
will ignore it and does not perform a reset function.
The LVR uses the
OR function with the external
RES signal to perform chip reset.
The relationship between VDD and VLVR is shown below.
Note:
VOPR is the voltage range for proper chip opera-
tion at 4MHz system clock.
