Section 12 Data Transfer Controller (DTC)
12.2.6
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 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.
12.2.7
DTCER, which is comprised of eight registers, DTCERA to DTCERF, is a register that specifies
DTC activation interrupt sources. The correspondence between interrupt sources and DTCE bits is
shown in table 12.1. Use bit manipulation instructions such as BSET and BCLR to read or write a
DTCE bit. If all interrupts are masked, multiple activation sources can be set at one time (only at
the initial setting) by writing data after executing a dummy read on the relevant register.
