Note 1) tsys indicates the three values below according to the upper two bits (CPU clock selection) of the
control clock register (address: 00FEH).
tsys (ns) = 2000/fc (upper two bits = "00"), 4000/fc (upper two bits = "01"), 16000/fc (upper two bits = "11")
Note 2) The load condition for the SCK0 (SCK1) output mode, SO0 (SO1) output delay time is 50pF + 1TTL.
