Port Bit Latches and I/O buffers 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: Register Content ACC 00h B 00h DPTR 0000h EICON 00h HWDR 00h IE 0X000000b IP XX000000b MSCON XXXXXXX0b MXCR0–1 00h P0–P3 FFh |
