„ Remote Receiver Circuit (share with P73/INT3/T0IN terminal)  
Noise rejection function (The filtering time of the noise rejection filter (1tCYC/32 tCYC/128 tCYC) can be switched  
by program.)  
„Watchdog Ttimer  
External RC circuit is required.  
Interrupt or system reset is activated when the timer overflows.  
„Interrupts  
27-source and 10-vectored interrupt function :  
1. Three interrupt priorities, low (L), high (H) and highest (X) are supported with multi-level nesting possible.  
During interrupt handling, an equal or lower level interrupt request is refused.  
2. If interrupt requests for two or more vector addresses occur at once, the higher level interrupt takes  
precedence. In the case of equal priority levels, the vector with the lowest address takes precedence.

Minimum instruction cycle time (300ns, 600ns, 1.2µs, 4.8µs, 9.6µs, 19.2µs, 38.4µs, 76.8µs can be switched by  
program (when using 10MHz main clock)  
„Standby Function  
HALT mode  
The HALT mode stops program execution while the peripheral circuits keep operating and minimizes power  
consumption. This operation mode can be released by a system reset or an interrupt request.  
HOLD mode  
The HOLD mode stops program execution and all oscillation circuits : CF, RC and Crystal oscillations.  
This mode can be released by the following conditions.  
1. Supply "L" level to the reset terminal (RES)  
2. Supply the selected level to at lease one of INT0, INT1, INT2, INT4, INT5.  
3. Supply an interrupt condition to Port 0.  
X’tal HOLD mode  
The X’tal HOLD mode stops program execution and all peripheral circuits except for the base timer. The crystal  
oscillator maintains its state at HOLD mode inception. This mode can be released by the following conditions.  
1. Supply "L" level to the reset terminal (RES).  
2. Supply the selected level to at least one of INT0, INT1, INT2, INT4, INT5.  
3. Supply an interrupt condition to Port 0.  
4. Supply an interrupt condition to the base timer circuit.

starts the sub-clock oscillator or after releasing a HOLD mode. (Refer to Figure 4)  
Notes : Since the oscillation frequency precision is affected by the circuit pattern, place the oscillation related parts as  
close to the oscillation pins as possible, using the shortest possible pattern length.
