Mesa 7I90HD - 7 I90 Hd Supported Memory Spaces; Space0: Hostmot2 Registers

7I90HD 29
REFERENCE INFORMATION
LBP16
7I90HD SUPPORTED MEMORY SPACES
The 7I90HD firmware supports 7 address spaces. These will be described
individually with example hexadecimal commands. The hex command examples below are
written in LSB first order for convenienc5901e. In the hex command examples, the NN is
the count/increment field of the LBP16 command and the LLHH is the low and high bytes
of the address.
SPACE 0: HOSTMOT2 REGISTERS
This address space is the most important as it gives access to the FPGA I/O. This
is a 64K byte address range space with 32 bit R/W access.
Space 0 read with address NN42LLHH
Space 0 write with address NNC2LLHH
Space 0 read NN02
Space 0 write NN82
