LC87F2C64A
„Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
(1) Oscillation is not halted automatically.
(2) There are three ways of resetting the HALT mode.
1) Setting the reset pin to the lower level
2) System resetting by watchdog timer
3) Occurrence of an interrupt
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
(1) The CF, RC, crystal, and frequency variable RC oscillators automatically stop operation.
(2) There are five ways of resetting the HOLD mode.
1) Setting the reset pin to the lower level
2) System resetting by watchdog timer
3) Setting at least one of the INT0, INT1, INT2, INT3, INT4, INT5 pins to the specified level
4) Having an interrupt source established at port 0
5) Having an interrupt source established in SPI receiving 1-byte (8-bit clock)
• X’'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
(1) The CF, RC, and frequency variable RC oscillators automatically stop operation.
(2) The state of crystal oscillation established when the X’tal HOLD mode is entered is retained.
(3) Power-save mode is available for even lower current consumption.
(4) There are seven ways of resetting the X’tal HOLD mode.
1) Setting the reset pin to the low level
2) System resetting by watchdog timer
3) Setting at least one of the INT0, INT1, INT2, INT3, INT4, INT5 pins to the specified level
4) Having an interrupt source established at port0
5) Having an interrupt source established in the base timer circuit
6) Having an interrupt source established in the RTC
7) Having an interrupt source established in SPI receiving 1-byte (8-bit clock)
„On-chip Debugging Function (flash ROM version)
• Supports software debugging with the test device installed on the target board.
„Data Security Function (flash ROM version)
• Protects the program data stored in flash memory from unauthorized read or copy.
Note: The data security function does not necessarily provide an absolute data security.
