CPU
The GMS90 series is efficient both as a controller and as an arithmetic processor. It has extensive facilities
for binary and BCD arithmetic and excels in its bit-handling capabilities. Efficient use of program memory
results from an instruction set consisting of 44% one-byte, 41% two-byte, and 15% three-byte instructions.
With a 12 MHz crystal, 58% of the instructions are executed in 1.0
