PROGRAMMING FLAG OFFSETS
72V2113 has 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
the LD (Load) pin. During Master Reset, the state of the LD input determines
whether serial or parallel flag offset programming is enabled. A HIGH on LD
during Master Reset selects serial loading of offset values. A LOW on LD during
Master Reset selects parallel loading of offset values.
the current offset values. Offset values can be read via the parallel output port
Q0-Qn, regardless of the programming mode selected (serial or parallel). It is
not possible to read the offset values in serial fashion.

MRS), the PAF is asserted and updated on the rising edge of WCLK only and
not RCLK. Similarly, PAE is asserted and updated on the rising edge of RCLK
only and not WCLK. For detail timing diagrams, see Figure 18 for synchronous
PAF timing and Figure 19 for synchronous PAE timing.
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
20 for asynchronous PAF timing and Figure 21 for asynchronous PAE timing.
