GENERAL DESCRIPTION
The WT6016 is a member of WT60XX microcontroller family. It is specially designed for digital con-
trolled multi-sync monitor. It contains 8-bit CPU, 16K bytes ROM, 288 bytes RAM, 14 PWMs, parallel I/
O, SYNC processor, timer, one DDC interface (slave mode I²C interface with DDC1), one master/slave
I²C interface, two 4-bit A/D converters and watch-dog timer.
