Some records omit this field ( n equals zero). Data, a sequence of n bytes of data, represented by 2 n hex digits. Record type (see below), two hex digits, 00 to 05, defining the meaning of the data field. The base address, which defaults to zero, can be changed by various types of records.īase addresses and address offsets are always expressed as values. The physical address of the data is computed by adding this offset to a previously established base address, thus allowing memory addressing beyond the 64 kilobyte limit of 16-bit addresses. Address, four hex digits, representing the 16-bit beginning memory address offset of the data. 16 (0x10) and 32 (0x20) are commonly used byte counts.

Byte count, two hex digits (one hex digit pair), indicating the number of bytes (hex digit pairs) in the data field. Start code, one character, an ASCII colon ':'. Each text line is called a record.Record structure A (line of text) consists of six (parts) that appear in order from left to right. The binary numbers may represent data, or other values, depending on their position in the line and the type and length of the line. Each text line contains characters that multiple binary numbers. Contents.Format Intel HEX consists of lines of text that are separated by or characters or both.
