Device status on MISO
control bit into the device, MISO pin reports a 16 bits fixed
device status composed of 2 bytes: Device Fixed Status (bits
15 to 8) + extended Device Status (bits 7 to 0). In a read
operation, MISO will report the Fixed device status (bits 15 to
8) and the next 8 bits will be the content of the selected
register.
In addition some of the registers are used to report device

Bit 8 must be set to 1, independently of the parity function
selected or not selected.
If bit 8 is set to “0”: means parity not selected OR
parity is selected AND parity = 0
if bit 8 is set to “1”: means parity is selected AND parity = 1
Bit 8 must be set to 1, independently of the parity function
selected or not selected.
