LC866548/40/32/28/24A
(14) Multiplication and division
- 16 bit × 8 bit (7 instruction cycle times)
- 16 bit ÷ 8 bit (7 instruction cycle times)
(15) Three oscillation circuits
- On-chip RC oscillation circuit used for the system clock
- On-chip CF oscillation circuit used for the system clock
- On-chip Crystal oscillation circuit used for the system clock and for time-base clock
Note : External resisters (Rf, Rd) are required
(16) Standby function
- HALT mode function
The HALT mode is used to reduce the power dissipation. In this operation mode, the program execution is stopped.
This operation mode can be released by the interrupt request signals or the initial system reset request signal.
- HOLD mode function
The HOLD mode is used to stop 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.
• Input a assigned level to P70/INT0/T0IN or P71/INT1/T0IN terminal.
• Input a Port0 interrupt condition.
