(13) Real-time service operation
The Real-Time Service (RTS) functions the 4-byte data-transfer between the Special Function Registers at
acknowledging the interrupt request.
The RTS starts within 1 instruction cycle-time and completes within 5 instructions cycle-time after occurring the
interrupt request.
(14) Subroutine stack levels

- On-chip CF oscillation circuit using for the system clock.
- On-chip crystal oscillation circuit using for the system clock and for time-base clock.
(17) Standby function
- HALT mode function
The HALT mode is used to reduce power dissipation. In this operation mode, program execution is stopped. This
operation mode can be released by interrupt request signals or the initial system reset request signal.
- HOLD mode function
The HOLD mode is used to freeze all the oscillations;
RC (internal), CF and Crystal oscillations. This mode can be released by the following operations.
• Reset terminal ( RES ) set to Low level
• P70/INT0/T0IN, P71/INT1/T0IN terminals set to assigned level (programmable)
• Input a Port 0 interrupt condition
