Programming enable and transition registers
The only registers that can be programmed by the user are the enable and
transition registers. All other registers in the status structure are read-only
registers.
To determine the parameter values for the various commands used to program
enable registers, a command to program an event enable or transition register is
sent with a parameter value that determines the desired state (0 or 1) of each bit
in the appropriate register. The bit positions of the register (see the following
figure) indicate the binary parameter value and decimal equivalent. To program
one of the registers, send the decimal value for the bit(s) to be set.
Figure 12-8: 16-bit status register
When using a numeric parameter, registers are programmed by including the
appropriate <mask> value, for example:
*ese <mask>
status.standard.enable = <mask>
To convert from decimal to binary, use the information shown in the figure
above.
For example, to set bits B0, B4, B7, and B10, a decimal value of 1169 would be
used for the mask parameter (1169 = 1 + 16 + 128 + 1024).
