24.3.13 Transfer Block Number Counter (TBNCR)
A value other than 0 must be written to the TBNCR register if a multiple block transfer is selected
through the TY5 and TY6 bits in the CMDTYR. Set the transfer block number in the TBNCR.
The value of TBNCR is decremented by one as each block transfer is executed and the command
sequence ends when the TBNCR value equals 0.
