Note 1)
t
sys indicates three values according to the contents of the clock control register (CLC; 00FE
H
) upper
2 bits (CPU clock selection).
t
sys [ns] = 2000/fc (upper 2 bits = “00”), 4000/fc (upper 2 bits = “01”), 16000/fc (upper 2 bits = “11”)
Note 2)
CS, SCK, SI and SO represent CS0, SCK0, SI0 and SO0, respectively.
Note 3)
The load of SCK output mode and SO output delay time is 50pF.
