Programmable Registers
6.5.116 APBH DMA channel 15 Buffer Address Register
The APBH DMA channel 15 buffer address register contains a pointer to the data buffer
for the transfer. For immediate forms, the data is taken from this register. This is a byte
address which means transfers can start on any byte boundary.
Because channel 15 is not assigned to any peripheral, this register is of no practical usage
and just reserved for compatibility.

6.5.117 APBH DMA channel 15 Semaphore Register
The APBH DMA channel 15 semaphore register is used to synchronize between the CPU
instruction stream and the DMA chain processing state.
Because channel 15 is not assigned to any peripheral, this register is of no practical usage
and just reserved for compatibility.
