• Note:
abtpri_r0 bits. If the same priority values are set, you will not be able to set 1 to abt_en.
<Relationship of DMAC and the priority area of the Arbiter Setting register>
and one DMAC for Master Read (DMAC_R0). The second DMAC for Master Write
(DMAC_W1) and the second DMAC for Master Read (DMAC_R1) are not supported.
Accordingly, setting priority for DMAC_W1 and DMAC_R1 has virtually no meaning,
but you should be sure to set different priority values for the abtpri_w1, abtpri_w0,
abtpri_r1, and abtpri_r0 bits as mentioned above. There will be no problem to set
values for the corresponding register areas of an unpackaged DMAC. The priority
areas of Arbiter Setting register correspond with DMAC as shown below.
Be sure to set different priority values for the abtpri_w1, abtpri_w0, abtpri_r1, and
Current UDC2AB specification supports one DMAC for Master Write (DMAC_W0)
