20.5
In the GDTA, there are four types of interrupt sources. There are three interrupt flags for CL
processing end, MC processing end, and CL/MC errors, used to identify interrupt sources. The
interrupt enable bit allows generation of interrupt requests.
CL errors and MC errors use a common GAERI interrupt.
Table 20.10 GDTA Interrupt Request
20.6
The GDTA performs data alignment conversion of input data, output data, and RAM 0/1 data
using an endian signal (pin MD8) or using GDTA internal registers.
Table 20.11 shows the correspondence between data alignment conversion patterns and the
settings of DRCL_CTL, DWCL_CTL, DRMC_CTL, DWMC_CTL, DCP_CTL, and DID_CTL.
