This is divided into the following clocks: * CPU "high" clock speed = master clock / 3 (approx. 7.15909 MHz), * CPU "low" clock speed = master clock / 12 (approx. 1.78978 MHz), * Timer speed = master clock / 3072 (approx. 6.991 KHz), * VCE pixel clocks: ** "10MHz" = master clock / 2, ** "7MHz" = master clock / 3, ** "5MHz..." current
