1. DESCRIPTION  
Pulse duty detection circuit (VISS and VASS signal detection  
features embedded) Measures PBCTL signal duty ratio.  
Synchronous signal separation circuit  
This microcomputer is a single-chip microcomputer that adopts a  
high-performance silicon gate CMOS process, and is contained in  
a 100-pin plastic mold QFP. This single-chip microcomputer is pro-  
vided with an instruction queue buffer and a data buffer for  
executing instructions at high speed. The central processing unit  
runs in a 16-bit parallel processing mode but can be converted  
into an 8-bit parallel processing mode when necessary. This prod-  
uct has been designed exclusively for video equipment system  
controls, incorporating a time measuring circuit for VCR servo  
control, a real-time pattern generating circuit, analog amplifiers, an  
OSD display circuit, and a data slicer, among its many other pe-  
ripheral capabilities.
