Description
Power supply pin. Connect it to the system power supply. Connect
this pin to VSS via a 0.1-µF capacitor. The capacitor should be
placed close to the pin
Connect this pin to VSS via a 0.1-F capacitor. The capacitor
should be placed close to the pin
Ground pin. Connect it to the system power supply (0 V)
Backup power pin. When the battery backup function is not to be
used, connect it to the VCC pin.
Pins for a crystal resonator. An external clock signal can be input
through the EXTAL pin
Outputs the external bus clock for external devices
Input/output pins for the sub-clock oscillator circuit. Connect a
crystal resonator between XCOUT and XCIN
Pin for setting the operating mode. The signal levels on these pins
must not be changed during operation
Reset signal input pin. This LSI enters the reset state when this
signal goes low
Input pin for the on-chip emulator enable signal. When the on-chip
emulator is used, this pin should be driven high. When not used, it
should be driven low
Boundary scan enable pin. Boundary scan is enabled when this pin
goes high. When not used, it should be driven low
Fine interface clock pin
Fine interface pin
On-chip emulator or boundary scan pins. When the EMLE pin is
driven high, these pins are dedicated for the on-chip emulator
This pin outputs the clock for synchronization with the trace data
This pin indicates that output from the TRDATA0 to TRDATA3 pins
is valid
These pins output the trace information
Output pins for the address
Input and output pins for the bidirectional data bus
Address/data multiplexed bus
