11.6 Cell Data
The following tables define the Perfect Harmony Modulator/CCB communication data bytes where bit 0 is the least
significant bit (LSB). Table A-3 shows the information that flows from the Modulator card to the CCB. Table A-4
shows the CCB response message for each of the 4 data modes. The Operating Mode is controlled by the Harmony
microprocessor where Mode ‘00’ is the default mode. Modes ‘01’, ‘10’, and ‘11’ are used for diagnostic purposes
only. All data sent to the CCB is processed by the Cell Control Gal (U31), therefore the functionality of these ‘Up’
bits are totally dependent on the GAL logic.

Table 11-4: CCB to Modulator Data (‘Down’ Bits)
Note that the CCB is responsible for latching all CCB initiated fault conditions so that the Perfect Harmony CPU can
properly determine the cause of any CCB faults when cell diagnostics are performed. These CCB faults must remain
latched until a Cell Fault Reset is received by the CCB (bit 2 of Mode ‘01’ or ‘10’). The parity bit is “stripped off” at
the FOLA before getting to the Modulator cell data registers, and replaced with the OR’ed value of the parity fault
and the link fault (CommFault).
