System Integration Block (SIB)
(DAPR), an 8-bit function code register (FCR), a 16-bit byte count register (BCR), a 16-bit
channel mode register (CMR), and an 8-bit channel status register (CSR). These registers
provide the addresses, transfer count, and configuration information necessary to set up a
transfer. They also provide a means of controlling the IDMA and monitoring its status. All
registers can be modified by the M68000 core. The IDMA also includes another 16-bit reg-
ister, the data holding register (DHR), which is not accessible to the M68000 core and is
used by the IDMA for temporary data storage.
3.1.2.1 Channel Mode Register (CMR)
The CMR, a 16-bit register, is reset to $0000.
