Preliminary Data Sheet
November 2000
Codec Chip Set
T8531/T8532 Multichannel Programmable
Software Interface
(continued)
Table 33. Bits 15:8 of T8531 Board Control Word 1 at 0x1FFE
Table 34. Bits 7:0 of T8531 Board Control Word 1 at 0x1FFE
Notes:
All bits in board control register 1 will be zeros upon hardware reset.
In OSD loopback mode, OSDR0, OSDR1, OSDR2, and OSDR3 are looped back with a delay of two OSCLK clock cycles to OSDX0, OSDX1,
OSDX2, and OSDX3, respectively.
Test modes are for production testing only.
μ
-law/A-law companding mode provides 8 bits of PCM data with the first bit (bit 1) defined as the MSB and the last bit (bit 8) as the LSB. Bit 1 is
the sign bit, bits 2 through 4 are the chord bits, and bits 5 through 8 are the interval bits. In linear mode, the
μ
-law/A-law conversion in the PCM
interface block is disabled and 16 bits of linear PCM data are provided. In linear mode, bit 1 is the MSB and the sign bit, bits 2 through 14 are
the intervals, and bits 15 and 16 are insignificant. Each interval represents 0.0001362745 Vrms with 8031 intervals being the maximum signal
output of 3 dBm0. Negative values are two’s complement of positive values.
X = don’t care.
