FT/RST pin, frequency test and reset output pin (M41T82
only)
On the M41T82, the 512 Hz frequency test signal and the reset output share the same pin,
FT/RST. When the FT bit (bit 6 of register 08h) is a 1, the 512 Hz test signal is activated on
the pin. With FT a 0 and VCC good (above VRST), the output will be high. If the 512 Hz is
enabled when VCC fails, the FT bit will be cleared and the output will go low to assert reset.
At power-up, FT will be 0 leaving the pin functioning as the reset output.
