12.16: RXXLT Instruction Array Address Port
This register provides the read/write address for accessing the instruction array. When RXXLT Instruction
Array Read/Write Port is read/written, this register is auto-incremented. When the last address is read/written,
the address rolls over to zero.

12.17: RXXLT Instruction Array Read/Write Port
Provides read/write access to the instruction array. The instruction array is divided into four groups of 32
entries. Each group is associated with a receive port (0-3) so a nano-program can be loaded for each active
port. When this register is read/written, the address provided by RXXLT Instruction Array Address Port is
used to select the array word to be accessed. RXXLT Instruction Array Address Port is auto-incremented on
each read/write. Thus, this port can be read/written multiple times to read/write the entire array.
