Part Number: TCAN2451-Q1

Tool/software:

Hello team,

Customer needs to use standby for low power mode, pls support:

1. What mode will SBC enter in when wake pin  is triggered under standby mode?

2. After detecting the wake signal, will there be interrupt created in nFault pin?

Thanks!

    1. When a wake pin is triggered in Standby mode, wake interrupt is generated. nINT pin will go low (if it's not already low due to other interrupts) and wake interrupt bit (LWU, h'51[5]) will be set. The SBC does not do a mode change from Standby mode because MCU is already powered with VCC1. MCU has to take an action to change the mode to Normal mode if desired

    2. nINT pin will go low to indicate wake up interrupt if it's not already low due to other interrupts. In addition, wake-up is also indicated by RXD pin going low.
