Unit

tsys = 2000/fc

Condition

Note 1)

tsys indicates three values according to the contents of the clock control register (address; 00FEH)

upper 2 bits (CPU clock selection).

tsys [ns] = 2000/fc (Upper 2 bits = "00"), 4000/fc (Upper 2 bits = "01"), 16000/fc (Upper 2 bits = "11")

Note 2) The value of

tFRC is as follows by selecting FRC clock (FRCS: 01EEH bit 7)

When PS0 is selected,

tFRC = 1000/fc (ns)

When PS1 is selected,

tFRC = 2000/fc (ns)
