Programming the STPM10
Data records
The STPM10 has 8 internal data record registers. Every data record consists of a 4-bit
parity code and 28-bit data value where the parity code is computed from the data value,
which makes a total of 32 bits, or 4 bytes.
Figure 21
bit of parity nibble is defined as odd parity of all seven corresponding bits of data nibbles.
The first 6 registers are read-only, except for the 8-bit mode signals in the DFP register (the
mode signals are described later in this paragraph). The last two registers are CFL and
CFH.
Configuration bits
All the configuration bits that control the operation of the device (CFL and CFH data records)
can be written in a temporary way. The configuration bit values are written in the so-called
volatile memory, which are simple latches that hold the configuration data until the power is
on or until a reset condition occurs (both POR and remote reset).
As indicated in the data records table, the configuration bits are 56.
