16.4.2.7.3 QDMA Event Enable Clear Register (QEECR)
The QDMA event enable register (QEER) cannot be modified by directly writing to the register, in order to
ease the software burden when multiple tasks are attempting to simultaneously modify these registers.
The QDMA event enable clear register (QEECR) is used to disable events. Writes of 1 to the bits in
QEECR clear the corresponding QDMA channel bits in QEER; writes of 0 have no effect.
The QEECR is shown in
and described in
Figure 16-78. QDMA Event Enable Clear Register (QEECR)

16.4.2.7.4 QDMA Event Enable Set Register (QEESR)
The QDMA event enable register (QEER) cannot be modified by directly writing to the register, in order to
ease the software burden when multiple tasks are attempting to simultaneously modify these registers.
The QDMA event enable set register (QEESR) is used to enable events. Writes of 1 to the bits in QEESR
set the corresponding QDMA channel bits in QEER; writes of 0 have no effect.
The QEESR is shown in
