Signals/Connections
1.5 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.

Signal Description
MODA
IRQA
Input
Schmitt-trigger
Input
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.
MODB
IRQB
Input
Schmitt-trigger
Input
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.
MODC
IRQC
Input
Schmitt-trigger
Input
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.
MODD
IRQD
Input
Schmitt-trigger
Input
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.
RESET
Input
Schmitt-trigger
Input
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.
PINIT
NMI
Input
Schmitt-trigger
Input
PLL Initial—During assertion of RESET, the value of PINIT determines
whether the DPLL is enabled or disabled.
Nonmaskable Interrupt—After RESET deassertion and during normal
instruction processing, this Schmitt-trigger input is the negative-edge-triggered
NMI request.
