NJU6060
Ver.2004-04-16
(2) Instructions
3 line type serial interface using a setup of PWM data, ON/OFF of Light Emitting Diode, etc. are made.
The input data and latched at rising edge of chip shift clock (CLK) and the 8-bit data are fetched into the NJU6060 at
the rising edge of chip select (CS). The data to input is MSB first.
Table.1 shows the instruction codes of the NJU6060.

Test Data
Inhibited command
* : Don’t Care
Note) The “PWM data set”, the “PWM Frequency set” and the “PWM phase set” commands are executed, asynchronously
to the PWM counter, thus the user’s command setting is executed after execution time, which is about 128/fosc if
{“fPWM=(fosc/2)/2”} is set up. During that execution time, the IC may execute an unexpected setting. For this
reason, it is recommended to make sure actual performance is the user’s practical application.
(2-1) Explanation of instruction code
(a) LED1 to 3 PWM Data Set
This instruction set the PWM luminance control Duty data. It sets up for every LED port.
