MACC_yRELOAD
The MACC_yEND register, listed in
the MACC to read 16-bit values from the y DATA for performing its calculations.
The MACC_yRELOAD register, listed in
DATA of MACC RAM. When the y DATA address increments to the value in
MACC_yEND, the next y DATA address is taken from this MACC_yRELOAD register.
The MACC Control register, listed in
interrupt enable on completion of calculation. All writes to this register clear the 40-bit
accumulator to 0 (MACC_ACx =
