Hello Mahmoud,
The title is TPS659037 user's guide to power AM574x, AM572x, and AM571x (Rev. F) in product folder.
Can you open the below link?

Here is the delay for ON request. It is in the datasheet SLIS165G
ON Requests
ON requests are used to switch on the TPS659037 device, which transitions the device from the OFF to
the ACTIVE state. Table 5-9 lists the ON requests.
Table 5-9. ON Requests
EVENT MASKABLE POLARITY COMMENT DEBOUNCE
RPWRON (pin) No Low Level sensitive 16 ms ± 1 ms
PWRON (pin) No Low Level sensitive N/A
Part of interrupts
(event)
Yes (INTx_MASK register.
Default: Masked) Event Edge sensitive N/A
POWERHOLD (pin) No High Level sensitive 3 - 5 ms typical

Hi Mahmoud,
I understand a little around the event occurring, but what does debounce mean in this paragraph?
In addition, is there no regulation for N/A?

Hello Hideki,
I guess we can simply say it is a delay. During this delay an event (due to noise for example) is not considered. N/A means no debounce time. I hope this answers your question.
