Subject: [Qemu-devel] [PATCH v3 03/18] sdcard: fix the 'maximum data transfer rate' to 25MHz
Date: Tue, 23 Jan 2018 00:30:19 -0300 [thread overview]
Message-ID: <20180123033034.29493-4-f4bug@amsat.org> (raw)
In-Reply-To: <20180123033034.29493-1-f4bug@amsat.org>
To comply with Spec v1.10 (and 2.00, 3.01):
. TRAN_SPEED
for current SD Memory Cards that field must be always 0_0110_010b (032h) which is
equal to 25MHz - the mandatory maximum operating frequency of SD Memory Card.
