Hi all,
I have some questions about Reset function as follows;
Q1.While the H/W or S/W Reset is ON, I think the LED output will be OFF. For example, when RESET is executed, what is the delay time from the output low state to the LED output turning off?
Q2.If the voltage level of the strap is higher than 2V of VIH (min) of LED_Link at the time Reset is released, will that strap level be taken in as High?
Q3.Regarding the duration of the H/W Reset pulse, how long should Reset be low, especially when using only the internal pull-up resistor to set the Strap that is used together with the output, such as LED_LINK and LED_SPEED?
Q4. After power-on, is it necessary to use S/W Reset together with H/W Reset? Is H/W Reset alone sufficient?
Q5. When I want to set the high level by the internal pull-up of the LED_LINK and LED_SPEED straps under the condition that there is no external pull-up strap, the method to ensure and accelerate these settings is LED Direct Control Register (LEDCR), address Is it effective to execute S/W Reset after writing "1" to 0x18 [5:4] and [2:1] to force the LED output to High?
The polarity of the LED is designed to be Low active.
Thanks and Regads,
Toshi
