To Write to the Internal Registers:
To Read Internal Registers:
NOTE: After an indirect write to a single channel, the data
can be read at direct addresses 0 and 1 after 4 clock
periods.
Bits 0, 2, 4, 6 are the OR-ing together of the individual data
path. Saturation bits listed in *01Fh (Table 14). These bits
are latched when set. Awrite to *01F clears the bit(s).
1. Load the indirect write holding registers at direct address
2. Write the Indirect Write Address of the internal register
3. Wait 4 clock cycles before performing the next write to the
1. Write the Indirect Read Address of the internal register
2. Perform a read of the Indirect Read Holding Registers at

write strobe to transfer the contents of the Indirect Write
Holding Register into the Target Register specified by the
Indirect Address will be generated internally).

CHANNEL 3 STATUS. Bit 7 is always zero, bit 6 indicates data path saturation.
CHANNEL 2 STATUS. Bit 5 is always zero, bit 4 indicates data path saturation.
CHANNEL 1 STATUS. Bit 3 is always zero, bit 2 indicates data path saturation.
