Note 1)
tsys indicates the three values below according to the upper two bits (CPU clock selection) of the
clock control register (CLC: 00FEh).
tsys [ns] = 2000/fc (upper two bits = “00”), 4000/fc (upper two bits = “01”), 16000/fc (upper two bits = “11”)
Note 2) SCK, SI and SO indicates SCK1, SI1 and SO1, respectively.
Note 3) The load condition for the SCK1 output mode, SO1 output delay time is 50pF + 1TTL.
Note 4) The value when Port B output buffer capability switching register (BUFB: 01F4h) selects buffer
capability to normal.
