cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed
in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
(2) The pin descriptions for all external pins except the RF Transceiver pins listed in the above table are de-
scribed in the preceding MCU section.
(3) The INT and RST lines are internally connected to the MCU I/O pins PC2 and PC3 respectively for the
HT82M75REW and HT82K75REW devices.
