Overview
The LC87F5DC8A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of
83.3 ns, integrate on a single chip a number of hardware features such as 128K-byte flash ROM (onboard rewritable),
4K-byte RAM, onchip debugging function, two sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, two synchronous SIO ports
(with automatic block transmission/reception capabilities),an asynchronous/synchronous SIO port, two UART ports
(full duplex), four 12-bit PWM channels, an 8-bit 15-channel AD converter, a high-speed clock counter, a system
clock frequency divider, and a 29-source 10-vector interrupt feature.

Mode 1: 8-bit PWM with an 8-bit prescaler × 2-channels
Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs)
(toggle outputs also from the lower-order 8 bits)
