17.3.1.3 MMA MAC Multiply Counter Register
Y SIGNED
BIT 16
Y Operand Signed
—Determines whether the Y operand
is signed or unsigned. When set, the Y operand is a signed
value. When cleared, the Y operand is unsigned.
0 = Y operand is unsigned
1 = Y operand is signed
Reserved
Bits 15–3
Reserved—These bits are reserved and should read 0.
CACHE CLR
Bit 2
Cache Clear
—Clears the X operand cache and writes the
(base + index) register value into the cache block register.
0 = No effect
1 = Clear X operand cache and
write (base+index) register
value into the cache block
register
CACHE EN
Bit 1
Cache Enable
—Enables or disables the X operand cache.
0 = X operand cache is disabled
1 = X operand cache is enabled
OP EN
Bit 0
Operation Enable
—Initiates MAC operation and indicates
if the operation is complete. The operation does not start if
MMA_MAC_MULT register contains 0.
0 = MAC operation is complete
1 = Initiate MAC operation or MAC
operation is not complete

MULT COUNTER
Bits 15–0
Multiply Counter
—Determines the number of multiply operations that the MAC module
performs. For proper operation, this value must be an integer multiple of the
(MMA_MA 1) value.
