8.2.6
CRB is a 16-bit register that designates the number of times data is to be transferred by the DTC in
block transfer mode. It functions as a 16-bit transfer counter (1 to 65,536) that is decremented by 1
every time a block of data is transferred, and bit DTCEn (n = 15 to 0) corresponding to the
activation source is cleared and then an interrupt is requested to the CPU when the count reaches
H'0000. The transfer count is 1 when CRB = H'0001, 65,535 when CRB = H'FFFF, and 65,536
when CRB = H'0000.
CRB is not available in normal and repeat modes and cannot be accessed directly by the CPU.
