OPERATING MODE REGISTER (OMR)
The OMR is a 24-bit, read/write register divided into three byte-sized units. The first
two bytes (COM and EOM) control the chipÕs operating mode. The third byte (SCS)
controls and monitors the stack extension. The OMR control bits are shown in
. Refer to the
DSP56300
Family Manual
for a complete description of the OMR.
