LC87F14C8A
„High-speed Multiplication/Division Instructions
• 16 bits × 8 bits
(5 tCYC execution time)
• 24 bits × 16 bits (12 tCYC execution time)
• 16 bits ÷ 8 bits
(8 tCYC execution time)
• 24 bits ÷ 16 bits (12 tCYC execution time)
„Oscillation Circuits
• RC oscillation circuit (internal):
• CF oscillation circuit:
• Crystal oscillation circuit:
• PLL circuit (internal):
For system clock
For system clock, USB interface
For system clock, time-of-day clock
For USB interface (see Fig.5)
„Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
1) Oscillation is not halted automatically.
2) Canceled by a system reset or occurrence of an interrupt.
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The PLL base clock generator, CF, RC and crystal oscillators automatically stop operation.
2) There are four ways of resetting the HOLD mode.
(1) Setting the reset pin to the lower level.
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
(4) Having an bus active interrupt source established in the USB host controller circuit
• X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
1) The PLL base clock generator, CF and RC oscillator automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are five ways of resetting the X'tal HOLD mode.
(1) Setting the reset pin to the low level
(2) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level
(3) Having an interrupt source established at port 0
(4) Having an interrupt source established in the base timer circuit
(5) Having an bus active interrupt source established in the USB host controller circuit
„ROM correction function
• Executes the correction program on detection of a match with the program counter value.
• Correction program area size: 128 bytes
