Functions for saving Data in PC Memory

The P180X_FunA and P180X_FunB series functions are designed for continuous capture which
storing the data into main memory. The features for these P180X_FunA and P180X_FunB are
listed as follows:

Sampling A/D data with high speed (for example, 330K)

Continues capture for a long period (for example, 2.5 minutes continue)

A/D data save in the PC memory first, then analyze these data later
(memory size=330 k*60*2.5=330 k*150=49.5 M word=99 M bytes)

Refer to demo22.c for 330 k, 2.5 minutes, continuous capture using 99 M bytes of the PC
memory
The P180X_FunA is designed for two boards and the P180X_FunB (Figure 9-2) is designed for
single-board as follows:
P180X_FunA_Start
P180X_FunA_ReadStatus
