ZSSC3224 RES PIN

Dear,

ZSSC3224 datasheet states "Alternatively, the RES pin can be connected and used to control safe resetting of the ZSSC3224. RES is active-low; a VDD-VSS-VDD transition at the RES pin leads to a complete ZSSC3224 reset." My question what the Reset Pulse width is?

Another question, the datasheet also said the Res PIN is pull up internally. What's the resistance value typcically?

Best Regards,

Jarvis
