shows how an example structure of data types is mapped in

SIMA

TIC 505 memory

STRUCT

{

(A) Boolean

(B) Boolean

(D) Unsigned8

(E) Boolean

(F) Integer16

(G) Integer16

(H) Integer32

(I) Unsigned8

(J) Unsigned16

(K) Unsigned32

(L)

Floating Point

(M)

Octet String[6]

}

12345678910111213141516

******

Note:

represents bits or bytes skipped for alignment purposes. When the structure is read,

this data is not transmitted; when the structure is written, this data is written to the value 0.

X represents data values.

Octet String[5] and Octet String[6] behave identically

. Both transfer 6 bytes on both read and

write.
