PROGRAMMING FLAG OFFSETS
72V36110 have internal registers for these offsets. There are eight default offset
values selectable during Master Reset. These offset values are shown in Table
2. Offset values can also be programmed into the FIFO in one of two ways; serial
or parallel loading method. The selection of the loading method is done using

MRS), the PAF is asserted LOW on the LOW-to-HIGH transition of WCLK and
PAF is reset to HIGH on the LOW-to-HIGH transition of RCLK. Similarly, PAE
is asserted LOW on the LOW-to-HIGH transition of RCLK. PAE is reset to HIGH
on the LOW-to-HIGH transition of WCLK. For detail timing diagrams, see Figure
