ADDRESS BUS
NOTES:
ADDRESS BUS
4. RESET vector address shown for timing example
1. Represents the internal clocking of the OSC1 pin
2. IRQ pin edge-sensitive mask option
3. IRQ pin level- and edge-sensitive mask option
1. Power-on reset threshold is typically between 1 V and 2 V.
2. OSC1 line is meant to represent time only, not frequency.
3. Internal clock, internal address bus, and internal data bus are not available externally.
