‘Jump to any address’
2
The ‘jump to any address’ mode is entered when the reset pin is released to V
conditions are satisfied:
– IRQ at 2xV
DD
– TCAP1 at V
DD
– PD3 at V
for at least 30 machine cycles after reset
DD
– PD4 at V
for at least 30 machine cycles after reset
DD
This function allows execution of programs previously loaded in RAM or EEPROM using the
methods outlined in
Section
To execute the ‘jump to any address’ function, data input at port A has to be $CC and data input at
port B and port C should represent the MSB and LSB respectively, of the address to jump to for
execution of the user program. A schematic diagram of the circuit required is shown in
