Memory organization for the DC
The ISP1362 DC has a total of 2462 bytes of built-in buffer memory. This buffer
memory is multicon
fi
gurable to support the requirements of different applications. The
DC buffer memory is divided into 16 areas to be used by control OUT, control IN and
14 programmable endpoints.
Figure 7
provides a snapshot of the DC buffer memory.
