IDT82P2284
T1/J1 IBCD Detector Status (077H, 177H, 277H, 377H)
LBA:
matched with less than 600 bit errors in each 39.8ms.
LBD:
period.
matched with less than 600 bit errors in each 39.8ms.
T1/J1 IBCD Activate Code (078H, 178H, 278H, 378H)
ACT[7:0]:
ASEL[1:0] bits (b1~0, T1/J1-076H,...). The unused bits should be ignored. The ACT[7] bit is the MSB and compares with the first received code bit.
T1/J1 IBCD Deactivate Code (079H, 179H, 279H, 379H)
DACT[7:0]:
DSEL[1:0] bits (b3~2, T1/J1-076H,...). The unused bits should be ignored. The DACT[7] bit is the MSB and compares with the first received code bit.
