Note:
Turbo PMAC 24-bit registers are copied into the low 24 bits of a 32-bit DPRAM
word. Bit 23 is sign-extended into bits 24 – 31. Turbo PMAC 48-bit registers are
treated as 2 24-bit registers. Each 24-bit register is copied into the low 24 bits of a
32-bit DPRAM word. Bit 23 is sign-extended into bits 24-31. The host computer
must re-assemble these values into a single fixed-point or floating-point value.
