INTERNAL READ ACCESS
A read is performed by first writing the CAR and AMR as with
a write. The data registers (DR2
–
DR0) are then read in the reverse
order that they were written. First, the least significant byte of
the data (D[7:0]) is read from DR0. On this transaction, the
high bytes of the data are moved from the internal address
pointed to by the CAR and AMR into the remaining data regis-
ters (DR2
–
DR1). This data can then be read from the data
registers using the appropriate 3-bit addresses. The number of
data registers used depends solely on the amount of data to be
read or written. Any unused bit in a data register should be
masked out for a read.
Read Pseudocode
int read_micro(ext_address);
main();
{
/
*
This code shows the reading of the first RCF coefficient using
the read_micro function as defined above. The variable address
is the External Address A[2..0].
Internal Address = 0x000
*
/
// holding registers for the coefficient
int d2, d1, d0;
// coefficient (20-bits wide)
long coefficient;
// write AMR
write_micro(7, 0x00);
// write LAR
write_micro(6, 0x00);
/
*
read D[7:0] from DR0, All data is moved from the Internal
Registers to the interface registers on this access
*
/
d0 = read_micro(0) & 0xFF;
// read D[15:8] from DR1
d1 = read_micro(1) & 0xFF;
// read D[23:16] from DR2
d2 = read_micro(2) & 0x0F;
coefficient = d0 + (d1 << 8) + (d2 << 16);
} // end of main
