(a) Address for storing buffer specifications (2 bytes)
A buffer from which data is to be read is specified. Up to 10 buffers
can be specified. Specify the address where the buffer specification
is held.
NOTE
For the method of buffer registration, refer to the relevant
MMC–III manual.
(b) Address for storing an offset from the beginning of a buffer (2 bytes)
An offset from the beginning of a read buffer is specified. Specify
the address where the offset is held.
(c) Data length storage address (2 bytes)
The length of data to be read from the MMC–III is specified. Specify
the address where the length of data is held. The maximum allowable
data length is 256 bytes.
(d) Input data storage address
Specify the address where data to be read from the MMC–III is
stored. A contiguous area not smaller than the length of data
specified in c) above is required.
W1=0 :When ACT = 0, W1 = 0 is set. If W1 = 0 is set when ACT = 1,
it indicates that read processing is in progress.
W1=1 :Indicates that read processing has terminated. Whether read
processing has terminated normally or abnormally can be
checked with the state of R9000 described below.
When W1 indicates the termination of read processing, a termination state
is set.
R9000
76543210
MMC3R error
MMC3R=0 : Normal termination
MMC3R=1 : Abnormal termination
When ACT = 1, completion status information is set in the operation
register R9002.
11 : MMC initialization not completed (W1=0, R9000#0=0)
0 : Normal termination (W1=1, R9000#0=0)
2 : Data length error (W1=1, R9000#0=1)
The specified length of data is 0, negative data is specified, or
the maximum allowable data length is exceeded.
6 : The MMC–III is not attached. (W1=1, R9000#0=1)
3 : Buffer specification error (W1=1, R9000#0=1)
