Note 1)
t
sys indicates the three values below according to the upper two bits (CPU clock selection) of the
clock control register (address: 00FE
H
).
t
sys [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 output mode, SO0 output delay time is 50pF + 1TTL.
(2) Serial transfer (CH0)
(Ta = –10 to +75°C, V
DD
= 4.5 to 5.5V, Vss=0V reference)
