1 - There has been at least one biphase error associated with incoming AES3 data during the input of the
last AES3 data block.
BLK_PERR - Block Parity Error. Updated on DETC boundaries
0 - There has been no parity error associated with incoming AES3 data during the input of the last AES3
data block.
1 - There has been at least one parity error associated with incoming AES3 data during the input of the
last AES3 data block.
11.23 Fs/XTI Ratio (17h - 18h)
FS_XTI[15:0] - 256*Fs/XTI, where Fs is the sample rate of incoming AES3-compatible data.
The integer part of FS_XT[15:0] is represented in bits [15:10] in register 17h, and the fractional part is rep-
resented in bits [9:0] of registers 17h and 18h; with a precision of 300 Hz in Fs and is updated approxi-
mately every 2048/(XTI frequency). Reading register 17h will cause the value of 18h to freeze until
register 18h is read.
11.24 Q-Channel Subcode (19h - 22h)
Each byte is LSB first with respect to the 80 Q-subcode bits Q[79:0]. Thus bit 7 of address 19h is Q[0] while
bit 0 of address 19h is Q[7]. Similarly bit 0 of address 22h corresponds to Q[79].
