The last register's complemented output is fed back to the first register's input. The output signal is derived from one or more of the register outputs. For example, a divide-by-6 divider can be constructed with a 3-register Johnson counter. The six valid values of the counter are 000, 100, 110, 111, 011, and 001.
decade counter (separate divide-by-2 and divide-by-5 sections) 14 SN74LS90: 74x91 1 8-bit shift register, serial in, serial out, gated input 14 SN74LS91: 74x92 1 divide-by-12 counter (separate divide-by-2 and divide-by-6 sections) 14 SN74LS92: 74x93 1 4-bit binary counter (separate divide-by-2 and divide-by-8 sections); different pinout for ...
This frequency, divided by 2 16 (the largest divisor the 8253 is capable of) produces the ≈18.2 Hz timer interrupt used in MS-DOS and related operating systems. In the original IBM PCs, Counter 0 is used to generate a timekeeping interrupt. Counter 1 is used to trigger the refresh of DRAM memory. Counter 2 is used to generate tones via the PC ...

In revision 1.2, released in 2013, a new "Reduced Blanking Timing Version 2" mode was added which further reduces the horizontal blanking interval from 160 to 80 pixels, increases pixel clock precision from ±0.25 MHz to ±0.001 MHz, and adds the option for a 1000/1001 modifier for ATSC/NTSC video-optimized timing modes (e.g. 59.94 Hz instead ...
Obesity dipped slightly in U.S. adults last year for the first time in more than a decade, a study found. The researchers suggested that might be due, in part, to the rise of weight loss drugs ...
