Data Sheet
RSC-4128
One may also interface to serial memory devices for storage and retrieval of speech data, by using the serial
drivers for ROM, Flash, EEPROM, etc. provided in the Sensory Speech 7 Technology Library. The serial memory
option is useful for applications of the RSC4128 packaged in a 64LQFP (which lacks the external parallel bus) for
which speech or music data exceed the storage capacity of on chip ROM. Using serial ROM, Flash or EEPROM
may result in a simpler, smaller PCB layout and lower overall system cost. The specific I/O used by the serial
interface are configurable. (See the “Sensory Speech 7 Technology Library Manual” for more information). An
example of the optional use of external serial Flash is provided in Reference Schematic 1-1.
Constant/Code Space
When reading, Constant/Code Space can be either internal to the chip or external. Typical uses of this space are
for code storage, and SI recognition set and/or compressed speech constant data storage. When the –XM input
pin is held low, Constant/Code Space is external to the chip when reading and –RDR is the read strobe. When the
–XM pin is high, Constant/Code Space reads are always internal to the chip, and are limited to the physical size of
the internal ROM.
When writing, –WRC is the write strobe regardless of the state of the –XM pin. Writing to Constant/Code Space
requires the
MOVC
instruction, which is limited to the first 128KBytes of Constant/Code Space.
When reading Constant/Code Space, an application can access up to 1MByte. However, only the first 128KBytes
can be used by the processor for program instructions (Code). The
MOVC
instruction can only read these first
128KBytes. These first 128KBytes are partitioned into 64Kbyte banks, called Code Bank 0 and Code Bank 1.
(NOTE: Code using both banks up to 128KBytes must provide “mirror” code in both banks for routines such as
Interrupt Service, etc, with protocols to track bank identity.) The
MOVX
instruction can read the full 1Mbyte.
However, the
MOVC
is more efficient for reading Constants within the current Code Bank.
The entire 1MByte of Constant/Code Space can be read with the following conditions. The upper addresses
A[19:16] are generated from Bits[3:0] of Extended Addressing Register (register D2):
1) The
MOVX
instruction is used to read and Bit 4 (“rw”) of Extended Addressing
Register (register D2) is programmed to “0”.
The first 128KBytes (addresses 00000H-1FFFFH; Code Banks 0 & 1) can be accessed in two additional ways. For
these two cases, addresses A[19:17] are forced to zero by the RSC4x, and A[16] is generated from Bit 5 (“cb1”) of
the Extended Addressing Register. A “0” in “cb1” selects Code Bank 0 and a “1” selects Code Bank 1:
2) The processor fetches instructions from the active Code Bank.
3) The
MOVC
instruction is used to read from or write to the active Code Bank.
Data Space
Data Space is always external to the chip and can be up to 1MByte. Typical uses of this space are for storage of
SD recognition template data and/or recorded audio data, and frequently the data is volatile. –RDF is the read
strobe and –WRD is the write strobe. A special bit in the Extended Addressing Register must be set high to allow
the processor to read from the data space using the
MOVX
instruction. When the “rw” bit (Bit 4 of Register D2) is
set, the
MOVX
instruction reads from the Data Space.
When writing to Data Space, the
MOVX
instruction generates a –WRD strobe, regardless of the state of the “rw” bit.
Data space can be accessed in two ways. For both cases, upper addresses A[19:16] are generated from bits [3:0]
of Extended Addressing Register:
1) The
MOVX
instruction is used to read and bit 4 (“RW”) of Extended
Addressing Register (register D2) is programmed to “1”.
2) The
MOVX
instruction is used to write.
