10.1 TMS320C32 Memory Features
The ’C32 external memory interface includes the following features:
-
One external pin, PRGW, configures the external-program-memory width
to 16 or 32 bits.
to 16 or 32 bits.
-
Two sets of memory strobes (STRB0 and STRB1) and one IOSTRB allow
zero glue-logic interface to two banks of memory and one bank of external
peripherals.

Each memory STRB handles 8-, 16- or 32-bit external data accesses
(reads and writes) to 8-, 16-, or 32-bit-wide memory.

Multiprocessor support through the HOLD and HOLDA signals, is valid for
all the STRBs.
