This unit incorporates one 16-bit up/down counter/timer channel (TMENC1) for 2-phase encoder input,
one 16-bit interval timer (TMM) channel, two 16-bit timer/event counter (TMQ) channels, and four 16-bit
timer/event counter (TMP) channels, and can measure pulse interval widths or frequency, enable an
inverter function for motor control, and output a programmable pulse.
A watchdog timer is equipped to detect program loops, system abnormalities, etc.
It generates a non-maskable interrupt request signal (INTWDT) or internal reset signal (WDTRES) after an
overflow occurs.
The V850E/IA3 includes four serial interface channels: for two asynchronous serial interface A (UARTA)
channels and two clocked serial interface B (CSIB) channels. Of these, UARTA1 and CSIB1 share a pin.
For UARTA, data is transferred via the TXDAn and RXDAn pins (n = 0, 1).
For CSIB, data is transferred via the SOBn, SIBn, and SCKBn pins (n = 0, 1).
One channel is provided for each of the high-speed, high-resolution 10-bit A/D converters ADC0 and
ADC1 (total of two channels), which have two and four analog input pins respectively, and one channel is
provided for the low-speed first-order ΔΣ conversion method 8-/10-bit A/D converter ADC2, which has six
analog input pins.
Both the ADC0 channels and three of the ADC1 channels include an operation amplifier and a comparator
so that these A/D converters can amplify an analog input voltage and detect overvoltage input.
A ROM correction function that replaces part of a program in the mask ROM or flash memory with a
program in the internal RAM is provided. Up to four correction addresses can be specified.
As shown below, the following ports have general-purpose port functions and control pin functions.
