ASCII Binary Format, Codes 01, 02, and 03(or 05, 06, and 07)

In these formats, bytes are recorded in ASCII codes with binary digits

represented by Ns and Ps, Ls and Hs, or 1s and 0s, respectively. See

Figure D-1. The ASCII Binary formats do not have addresses.

Figure D-1 shows sample data bytes coded in each of the three ASCII

Binary formats. Incoming bytes are stored in RAM sequentially starting

at the first RAM address. Bytes are sandwiched between B and F

characters and are separated by spaces.

Data can also be expressed in 4-bit words. The programmer generates the

4-bit format on upload if the data word width is 4 bits. Any other

characters, such as carriage returns or line feeds, may be inserted between

an F and the next B.

The start code is a nonprintable STX, which is a CTRL-B (the same as a

hex 02). The end code is a nonprintable ETX, which is a CTRL-C (the

same as a hex 03).

D-6 ProMaster 2500 User Manual

Note: Data without a start or end code may be input to or output from the

programmer by use of alternate data translation format codes. These are

ASCII-BNPF, 05; ASCII-BHLF, 06; ASCII-B10F, 07.

A single data byte can be aborted if the programmer receives an E

character between B and F characters. Data will continue to be stored in

sequential RAM addresses. Data are output in 4-byte lines with a space

between bytes.

Texas Instruments SDSMAC Format (320), Code 04

Data files in the SDSMAC (320) format consist of a start-of-file record,

data records, and an end-of-file record. See Figure D-2. The format is

used for Texas Instruments’ 320 line of processors. It is very similar to

format 90; the only difference is that the address fields represent 16-bit

data words rather than bytes

Each record is composed of a series of small fields, each initiated by a tag

character. the programmer recognizes and acknowledges the following

tag characters:

0 or K—followed by a file header.

7—followed by a checksum which the programmer acknowledges.

8—followed by a checksum which the programmer ignores.

9—followed by a load address which represents a word location.

B—followed by 4 data characters (16-bit word).

F—denotes the end of a data record.

*—followed by 2 data characters.

The start-of-file record begins with a tag character and a 12-character file

header. The first four characters are the word count of the 16-bit data

words; the remaining file header characters are the name of the file and

may be any ASCII characters (in hex notation). Next come interspersed

address fields and data fields (each with tag characters). The address

fields represent 16-bit words. If any data fields appear before the first

address field in the file, the first of those data fields is assigned to address

0000. Address fields may be expressed for any data word, but none are

required.
