Subject: [PATCH 1/4] wilc1000: use correct sequence of RESET for chip Power-UP/Down
Date: Fri, 13 May 2022 17:17:51 +0000 [thread overview]
Message-ID: <20220513171741.26701-1-ajay.kathat@microchip.com> (raw)
From: Ajay Singh <ajay.kathat@microchip.com>
For power-up sequence, WILC expects RESET set to high 5ms after making
chip_en(enable) so corrected chip power-up sequence by making RESET high.
For Power-Down sequence, the correct sequence make RESET and CHIP_EN low
without any extra delay.
