 TOBYTE (Convert WORD to BYTE)
Equation
Var1 = TOWORD (Var2, Var3)
Explanation
Convert Var3 number of WORD data from low-byte of Var2 to BYTE format and store
the result in Var1. This will discard high-byte of Var2.
Remark
 The calculation result can be stored as unsigned WORD.
 Var1 and Var2 can be internal memory only. Var3 can be internal memory or
constant.
 After data conversion is completed, the low and high bit of the converted WORD
data will be exchanged.
Example
Assume that the value of $0 is 12, this will convert 12 WORDS starting from the
low-byte of $4 and convert these 12 WORDS into 12 BYTES (6 WORDS) and store the
result in $10 to $16 (this is an operation of unsigned 16-bit data).
