• You cannot step into an interrupt
• Interrupts are disabled when the user program is halted
• The board cannot communicate with the host if interrupt nesting
is enabled.
• If you do not require the supplied monitor program, a start-up rou-

Serial Ports

The ADSP-2189M DSP features two synchronous bi-directional Serial
Ports (SPORTs),

30 Mbit/sec. SPORT data can be automatically transferred to and from
on-chip memory using DMA.

POST Routines

Power On Self-Test (POST) routines are a series of standard tests and ini-
tializations that the ADSP-2189M EZ-KIT Lite performs on a power-on
reset. To perform a power-on reset, disconnect power to the board for at
