C.2 S1 Type (Data Record: 2-Byte Address)
This is a record to store object data that can be represented in two bytes (0x0000 to
0xFFFF).

The S1 type consists of the above five fields (a) to (e).
(a):
Type field. "S1" (0x5331) in ASCII code.
(b):
Indicates the number of bytes in (c), (d), and (e).
(See the description in Appendix "C.1 S0 Type (Header Record)".)
(c):
Indicates the address allocated to the first data of (d).
a1 indicates the high-order digits and a4 indicates the low-order digits. Values in the range of 0 to 65535
can be set.
It is "0000" to "FFFF" in ASCII notation and "0x30303030" to "0x46464646" in hexadecimal notation.
(b):
Object data. Actual 1-byte data is represented by 2-byte ASCII code. In the above figure, d1 and d2 are
byte data at the address indicated by (c).
Likewise, d3 and d4 are byte data of the next address.
(e):
Checksum.
(See the description in Appendix "C.1 S0 Type (Header Record)".)
(f):
Generally, control code (such as CR and LF) is added.
(See the description in Appendix "C.1 S0 Type (Header Record)".)
