Mesa 7i92 - 7 I92 Supported Memory Spaces; Space0: Hostmot2 Registers

REFERENCE INFORMATION
LBP16
7I92 SUPPORTED MEMORY SPACES
The 7I92 firmware supports 6 address spaces. These will be described individually
with example hexadecimal commands. The hex command examples below are written in
LSB first order for convenience. 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
