3.6
The interrupt and mode control signals select the chip’s operating mode as it comes out of hardware reset.
After RESET is deasserted, these inputs are hardware interrupt request lines.

Table 6. Interrupt and Mode Control
Mode Select A/External Interrupt Request A—MODA/IRQA is an active-low
Schmitt-trigger input, internally synchronized to the DSP clock. MODA/IRQA
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 16 initial chip operating modes, latched into the OMR when the RESET
signal is deasserted. If the processor is in the stop standby state and the
MODA/IRQA pin is pulled to GND, the processor will exit the stop state.
Internal Pull up resistor.
This input is 5 V tolerant.
