Remarks 1.
Use of EP1_TCB is prohibited in the 8-bit external local bus mode. Clamp this signal to the inactive
status.
LD15 to 8 are undefined in the 8-bit external local bus mode (these signals are invalid when input and
undefined when output).
It is assumed that the external pin capacitance is 15 pF (data bus = 50 pF).
