5.5.2. PFC Data Memory Description
The structure of the data memory is shown in table 13. The first seven addresses of the PFC
controller's data memory hold general purpose registers which can be used in any combination to
execute commands in a minimum number of clock cycles. Note that register values are modified by
sine value computation and division. Consequently, their value must be rescued to data memory as
required. Address 8 through 15 provide access to eight constant read-only values. Addresses 16
through 29 are used for hardware ports which are described hereafter.
