The LCA (load configuration address) instruction stores the output of the AGU
as a configuration register address. When followed by RTC, the stored configuration
register address is the destination register, and when followed by CTR, it is the
source register.
Takes 1 cycles to execute.
Example: LCA
ASEL
----
LCA
AGU_ED ZERO 0x00000011 !! Generates 0x00000011 on the
!! output of the accumulator
LCA !! Loads configuration address
!! from the value of the accumulator,
!! i.e., 0x11
