Notes
1. When the value $FB occurs anywhere except in an ADDR header, it is repeated.
2. The data size is the number of bytes, prior to the $FB repetition, between the command code and the checksum inclusively.
3. The checksum applies to the “data size” bytes through the byte immediately before the checksum, inclusive. Repeated $FB’s
are counted only once. The sum is the two’s complement negative of the LS Byte of the arithmetic sum. For example, if the
sum is $1234, the checksum is $CC.
4. The parameter bytes are indexed using a 2-byte number (MSB first) starting with 0. The number of parameter bytes also uses
a 2-byte number with the same format. When sending parameters, the number sent is determined by the data size.
5. The working/stored flag is set if the working memory for either channel doesn’t match the stored memory from which it
originated.
6. The working/dirty flag is set when the ECS is powered up, or when a memory is recalled. It is cleared when the working
parameters are sent or received.
