4096byte RAM, Onchip debugging function, sophisticated 16-bit timers/counters (may be divided into 8-bit timers), a
16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a prescaler, a
base timer serving as a time-of-day clock, a high-speed clock counter, 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 system clock frequency divider, and a 29-source 10vector interrupt feature.

VDD1, VSS1 Terminal Condition
It is necessary to place capacitors between VDD1 and VSS1 as describe below.
• Place capacitors as close to VDD1 and VSS1 as possible.
• Place capacitors so that the length of each terminal to the each leg of the capacitor be equal (L1 = L1’, L2 = L2’).
• Place high capacitance capacitor C1 and low capacitance capacitor C2 in parallel.
• Capacitance of C2 must be more than 0.1μF.
• Use thicker pattern for VDD1 and VSS1.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after VDD
goes above the operating voltage lower limit (see Fig. 4).

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the
oscillation to get stabilized after the HOLD mode is reset (see Fig 4).
Note: The components that are involved in oscillation should be placed as close to the IC and to one another as possible
because they are vulnerable to the influences of the circuit pattern.
