1.6 Interrupt and Mode Control
The interrupt and mode control signals select the chip operating mode as it comes out of hardware reset. After
RESET is deasserted, these inputs are hardware interrupt request lines.

Reset—Places the chip in the Reset state and resets the internal phase
generator. The Schmitt-trigger input allows a slowly rising input (such as a
capacitor charging) to reset the chip reliably. When the RESET signal is
deasserted, the initial chip operating mode is latched from the MODA, MODB,
MODC, and MODD inputs. The RESET signal must be asserted after powerup.
Mode Select A—MODA, MODB, MODC, and MODD select one of 16 initial
chip operating modes, latched into the Operating Mode Register when the
RESET signal is deasserted.
External Interrupt Request A—After reset, this input becomes a level-
sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. If the processor is in the STOP or WAIT standby
state and IRQA is asserted, the processor exits the STOP or WAIT state.
Mode Select B—MODA, MODB, MODC, and MODD select one of 16 initial
chip operating modes, latched into the Operating Mode Register when the
RESET signal is deasserted.
External Interrupt Request B—After reset, this input becomes a level-
sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. If the processor is in the WAIT standby state and
IRQB is asserted, the processor exits the WAIT state.
Mode Select C—MODA, MODB, MODC, and MODD select one of 16 initial
chip operating modes, latched into the Operating Mode Register when the
RESET signal is deasserted.
External Interrupt Request C—After reset, this input becomes a level-
sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. If the processor is in the WAIT standby state and
IRQC is asserted, the processor exits the WAIT state.
Mode Select D—MODA, MODB, MODC, and MODD select one of 16 initial
chip operating modes, latched into the Operating Mode Register when the
RESET signal is deasserted.
External Interrupt Request D—After reset, this input becomes a level-
sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. If the processor is in the WAIT standby state and
IRQD is asserted, the processor exits the WAIT state.
