ePV6200
ePV6200 is VFD Controller manufactured by Elan.
description note, it includes important messages.)
1. There are some undefined bits in the registers. The values in these bits are unpredicted. These bits are not allowed to use. We use the symbol “-” in the spec to recognize them.
2. You will see some names for the register bits definitions. Some name will be appeared very frequently in the whole spec. The following describes the meaning for the register’s definitions such as bit type, bit name, bit number and so on.

.. e PV6200 VFD Controller
I. General Description
The e PV6200 is an 8 -bit RISC type VFD controller with low power, high speed CMOS technology. This integrated single chip has an on_chip watchdog timer (WDT), one time programming ROM (OTP), data RAM, programmable real time clock/counter, internal interrupt, power down mode, built-in four-wire SPI, IR detector and high voltage output for VFD application.
