Mcu=at89s8253
can engine=mcp2551
transduser=mcp2515
Why this win bridge oscillator circuit only has taken the frequency input from xtal1(pin 19) of mcu & if i connect my MCU
but I remove my CAN transducer & engine my MCU unnable to operate. Also when I connected my all component but instead...
Mcu=at89s82
can engine=mcp2551
transduser=mcp2515
when connecting a crystal between mcp2551(can engine) & at89s8253(mcu),
why xtal1(pin 19) of mcu taken as input from osc2(pin 7)of mcp2551?
WHY NOT XTAL2(PIN 18) OF MCU
WHY A RATING OF 10 uf capacitor is connected across reset(pin-9) of 8051 MC?
How a 10uf capacitor and 8.2kOhm resistor taking care to generate minimum 2 machine cycle in Oscillator to reset the Micro CONTROLLER ?
