LC87F2708A
„Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
1) Oscillation is not halted automatically.
2) There are the following three ways of resetting the HALT mode.
(1) Setting the reset pin to the low level
(2) Generating a reset signal via the watchdog timer or brown-out detector
(3) Having an interrupt generated
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The medium- and high-speed RC oscillation circuits automatically stop operation.
2) There are the following four ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower level.
(2) Generating a reset signal via the watchdog timer or brown-out detector
(3) Setting at least one of the INTA, INTB, INTC, INTD, INTE, and INTF pins to the specified level
(INTA and INTB HOLD mode reset is available only when level detection is set.)
(4) Applying input signals to the IN+ and IN- pins so that the analog comparator output is set to the specified
level (when the analog comparator output is assigned to the INTC input)
„On-chip Debugger Function
• Supports software debugging with the IC mounted on the target board (LC87D2708A).
LC87F2708A has an On-chip debugger but its function is limited.
• 3 channels of on-chip debugger pins are available.
„Data Security Function ^Note3
• Protects the program data stored in flash memory from unauthorized read or copy.
Note3: This data security function does not necessarily provide absolute data security.

Note4: On-board-programmer from FSG (AF9101/AF9103) and serial interface driver from SANYO (SIB87)
together can give a PC-less, standalone on-board-programming capabilities.
Note5: It needs a special programming devices and applications depending on the use of programming environment.
Please ask FSG or SANYO for the information.
