FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 24. DBUS Master Registers and Interrupt Block Diagram
DnH REGISTERS
These are read/write registers. There are two of these
registers, one for each of the buses, as shown in Figure 24.
When written to, the data is the high byte of a 9- to16-bit
command. When read, it is the high byte of a 9- to 16-bit
return on the DBUS. Writing to this register does not begin a
DBUS transaction. The low byte must be written to initiate the
DBUS transaction.
The bit assignments are shown in Figure 25. When a short
word of 8 bits is selected for the DBUS (MSn = 1), this register
is skipped in the SPI burst sequence. When the short word
length is set at other than 8 bits, this register will contain the
bits above eight, starting with the ninth bit in the least
significant bit position of the register. Unused bit positions are
don’t care values.
