NON-DISCLOSURE
AGREEMENT
REQUIRED
1.5.1 VDD and VSS
Power is supplied to the microcontroller’s digital circuits using these two
pins. V
DD is the positive supply and VSS is ground.
1.5.2 IRQ (Maskable Interrupt Request)
This pin has a user-specified mask option that provides one of two
different choices of interrupt triggering sensitivity. The options are:
1. Negative edge-sensitive triggering only
2. Both negative edge-sensitive and level-sensitive triggering
The MCU completes the current instruction before it responds to the
interrupt request. When IRQ goes low for at least one t
ILIH, a logic 1 is
latched internally to signify that an interrupt has been requested. When
the MCU completes its current instruction, the interrupt latch is tested. If
the interrupt latch contains a logic 1 and the interrupt mask bit (I bit) in
the condition code register is clear, the MCU then begins the interrupt
sequence.
If the option is selected to include level-sensitive triggering, the IRQ input
requires an external resistor to V
DD for wired-OR operation.
The IRQ pin contains an internal Schmitt trigger as part of its input to
improve noise immunity.
Refer to Section 4. Interrupts for more detail.
1.5.3 OSC1 and OSC2
The OSC1 and OSC2 pins are the control connections for the 2-pin on-
chip oscillator. The oscillator can be driven by any of the following:
Crystal resonator
Ceramic resonator
External clock signal
