6.5. Reset Circuitry
The reset circuitry for the TSC8051C1 is connected to
the reset pin RST. A Schmitt trigger is used at the input
for noise rejection (see Figure 5. ).
A reset is accomplished by holding the RST pin high for
at least two machine cycles (24 oscillator periods) while
the oscillator is running. The CPU responds by
executing an internal reset. It also configures the ALE
and PSEN pins as inputs (they are quasi–bidirectional).
A Watchdog timer underflow if enabled, will force a
reset condition to the TSC8051C1 by an internal
connection.
The internal reset is executed during the second cycle in
which reset is high and is repeated every cycle until RST
goes low. It leaves the internal registers as follows:
