Reset
Deassertion of RESET is internally synchronized to the clock out (CLKOUT). When
asserted, the chip is placed in the Reset state and the internal phase generator is
reset. The Schmitt-trigger input allows a slowly rising input (such as a capacitor
charging) to reset the chip reliably. If RESET is deasserted synchronous to CLKOUT,
exact start-up timing is guaranteed, allowing multiple processors to start and operate
synchronously. 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 power-up.
RESET can tolerate 5 V.
Mode Select A/External Interrupt Request A
Selects the initial chip operating mode during hardware reset and becomes a
level-sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. MODA/IRQA MODA, MODB, MODC, and MODD select
one of sixteen initial chip operating modes, latched into the OMR when the RESET
signal is deasserted.
Internally synchronized to CLKOUT. If IRQA is asserted synchronous to CLKOUT,
multiple processors can be re-synchronized using the WAIT instruction and asserting
IRQA to exit the Wait state. If a STOP instruction puts the processor is in the Stop
standby state and IRQA is asserted, the processor exits the Stop state.
MODA
Mode Select B/External Interrupt Request B
Selects the initial chip operating mode during hardware reset and becomes a
level-sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. MODA, MODB, MODC, and MODD select one of
sixteen initial chip operating modes, latched into OMR when the RESET signal is
deasserted.
Internally synchronized to CLKOUT. If IRQB is asserted synchronous to CLKOUT,
multiple processors can be re-synchronized using the WAIT instruction and asserting
IRQB to exit the Wait state.
MODB/IRQB can tolerate 5 V.
