Overview
The LC88F85D0A is a 16-bit microcomputer that, centered around an Xstormy16 CPU core, integrates on a single
chip a number of hardware features such as 256K bytes of flash ROM (onboard programmable), 8K bytes of RAM,
five 16-bit timers, a time base timer, a synchronous SIO interface with automatic transfer function, a single-master
I2C/synchronous SIO interface, two asynchronous SIO (UART) interfaces, a remote control receiver, LCD dedicated
RAM, an LCD dot-matrix driver, a 12-bit-resolution 8-channel AD converter, a watchdog timer, a system clock
frequency divider, and a 35-source 10-vector interrupt feature.

LC88F85D0A
Continued from preceding page.
HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) OSC1, RC, and OSC0 oscillations automatically stop.
2) There are five ways of releasing the HOLD mode:
<1> Setting the reset pin to the low level
<2> Having an interrupt source established at port 0
<3> Having an interrupt source established at SIO0
<4> Having an interrupt source established at UART2
<5> Having an interrupt source established at SEGINT
HOLDX mode: Suspends instruction execution and the operation of all the circuits except the peripheral circuits
running on OSC0.
1) OSC1 and RC oscillators automatically stop operation.
2) OSC0 retains the state established when the HOLDX mode is entered.
3) There are seven ways of releasing the HOLDX mode:
<1> Setting the reset pin to the low level
<2> Having an interrupt source established at port 0
<3> Having an interrupt source established at SIO0
<4> Having an interrupt source established at UART2
<5> Having an interrupt source established at SEGINT
<6> Having an interrupt source established in the base timer or RTC2 circuit
<7> Having an interrupt source established in the infrared remote control receiver circuit
