/*
SD/MMC status in R1, for native mode (SPI bits are different)
Type
e : error bit
s : status bit
r : detected and set for the actual command response
x : detected and set during command execution. the host must poll
the card by sending status command in order to read these bits.
Clear condition
a : according to the card state
b : always related to the previous command. Reception of
a valid command will clear it (with a delay of one command)
c : clear by read
