9.2 Registers

CR0a

Coefficient registers bank 0a

These seven 8-bit locations contain coefficients

which can be used by the third, of the three, 7-stage

mac arrays. CR0a(0) (address #000) corresponds

to the coefficient register of this mac array nearest

to its output. Similarly CR0a(6) (address #006)

corresponds to the coefficient register of this mac

nearest to its input. These Coefficient registers can

be written to provided that the other register bank

is in use. Whether the coefficient written is signed

or unsigned is determined by the ‘Unsigned Coef-

ficient’ bit SCR[3]. Once a value is written to a

coefficient register, its value can be read back from

an internal duplicate register. These registers will

be used by the mac array, when ACR[0], ‘Current

Bank’ is set to zero. Writing to these Coefficient

Registers while in use will result in an undefined

operation of the mac array.

CR0b

Coefficient registers bank 0b

These seven 8-bit locations contain coefficients

which can be used by the second, of the three,

7-stage mac arrays in the chain. CR0b(0) (address

#010) corresponds to the coefficient register of this

mac array nearest to its output. Similarly CR0b(6)

(address #016) corresponds to to the coefficient

haviour is otherwise identical to CR0a.
