Note 1: For 4-bit wide bus, wideShiftMask is 0x400000, CRC length is 64 bits
Note 2: If read data packet followed by another read data packet (block read), set
Note 3: Host interface will stop SCLK_OUT clock when needed to prevent transmit underrun or receive overrun. (not shown)
readDataMask = 0x40000. If only one read data packet, set readDataMask = 0.

For 1-bit wide bus, wideShiftMask = 0, CRC length is 16 bits.
