Scratch areas are memory areas that can be discarded when
μ
SAP77016-B08 is not operating. The user should
define scratch areas. A defined scratch area must be set using the a2d_InitDec function.
The user can use scratch areas when
μ
SAP77016-B08 is not operating. However, caution is required when using
these areas. Since
μ
SAP77016-B08 will use these areas again when it operates, if a user has set information in
scratch areas, the set information cannot be guaranteed.
Refer to Table 1-4 when using scratch areas.

A static area is a memory area that cannot be discarded even when
μ
SAP77016-B08 is not operating. A user
cannot use a static area.
Besides the memories described in Table 1-3, input buffer (X memory) and output buffer (X memory) are required.
In the sample program described later, 1024 words are used as an input buffer and 2048 words as two output
buffers, for a total of three buffers.
