example to memory area V, and then use area V for an access
that is more rapid (order of 5/10
µ
s).
5.12 Area of MMC
The memory area MMC is composed of
3000 words
. This is the
memory storage where it is possible to save large quantities of
data and maintain it even in the absence of power.
The memory is of type EEProm. The resulting access is thus
slower than area V and SM and the TD320 executes no control of
the integrity of the data stored in this area.
5.13 Area of TX/RX COM1
The memory area TX/RX COM1 is composed of
200 bytes
. This
area is used to manage the data in transit on serial port COM1.
The first 100 bytes (TX-0…TX-99) are used to load the data to
transmit; the last 100 bytes (RX-0…RX-99) are used to save the
data received by the serial port COM1.
These bytes are useful only in the free-port mode, while in normal
mode they are managed directly by the protocol selected in the
programming phase.
5.14 Area of TX/RX EXP1
The memory area TX/RX EXP1 is composed of
200 bytes
. This
area is used to manage the data in transit on the serial port EXP1.
The first 100 bytes (TX-0…TX-99) are used to load the data to
transmit, the last 100 bytes (RX-0…RX-99) are used to save the
data received by the serial port EXP1.
