* NOTES FOR SIMULATION\n \n--I2C communication and address related functions and pins are not modeled. \n \n--Changes to parameter values while the simulation is running will not take effect\n unless the simulation is stopped and restarted. This is different from the way\n the part operates which will respond to the changes while running.\n \n \nParameters A_REG and CD_REG can be defined by Ctrl + right click on the \nLTC3337 symbol.\n \nA_REG default of 65295 and CD_REG of 65530 will test this circuit with the over \ncounter IRQ pulling low in ~215ms. M is set by bits A[4:0] of A_REG and AMAX is \nset by bits A[15:8] of the A_REG. CD_REG set the initial count.
