A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), [1] is an electronic or software timer that is used to detect and recover from computer malfunctions. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant ...
RL78/G13 integrates a +/- 1% accuracy on-chip oscillator, watch dog timer, RTC, power-on reset, low voltage detection, 26 channels of 10bit ADC, 16x16 Multiplier, 32/32 Divider, I2C, CSI/SPI, UART, LIN, multi-function timer array and also built-in IEC 60730 safety support in hardware. This combination of elements enables the system designer to ...
Timers column - more recent families have wider timers and may allow chaining two 16-bit timers to do 32-bit capture. RTT is a 16-bit Real Time Timer that is driven by a 32.768KHz clock, though Microchip calls it RTC for Real Time Counter (easily confused to mean Real Time Clock).
A poll message is a control-acknowledgment message.. In a multidrop line arrangement (a central computer and different terminals in which the terminals share a single communication line to and from the computer), the system uses a master/slave polling arrangement whereby the central computer sends message (called polling message) to a specific terminal on the outgoing line.
The design minimizes and separates 32-bit arithmetic so that it can be adjusted or optimized for 8 and 16-bit CPUs. Also, 16-bit software timers (common on small microcontrollers) can overflow and cause defective operation. This can be fixed with a timer system that does not overflow (e.g. the timers count down or use modular arithmetic).
The Intel 809x/839x/879x ICs are 12 MHz, 16-bit microcontrollers. The microchip is based on a 5 V, 3 micrometre, HMOS process. The microcontroller has an on-chip ALU, 4 channel 10-bit analog-to-digital converter (ADC), 8-bit pulse width modulator (PWM), watchdog timer, 4 16-bit software timers, hardware multiply and divide, and 8 KB of on-chip ROM.
