HDMACBn (DMA Transfer Count B Setting Register)
The HDMACBn register is used to set the number of times a DMA request is to be
made. HDMACBn contains 16 bits and can specify up to 65536 requests (0001H = one
request, FFFFH = 65535 requests, 0000H = 65536 requests). When the transfer count
B is updated by DMA execution, HDMACBn is also updated.
HDMACB0 to HDMACB5 have the same configuration.
