FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
The value of RS also determines the last velocity position
step for which the Hold Counts are applied:
Last Velocity Position w/ Hold Counts = RS + 2
The number of hold counts per applicable velocity step is
determined by the value written to HC3:HC0 (HC) and can
range from 0 to 15 steps. This number of hold counts will be
applied to each step below the Hold Count Cut-In as
determined by HCP and RS. The default value of HC is 5.
Note: the following relationship between the variables
must be adhered to for the state machine to work properly:
HC x (HCP x 8 - 1) + (225 - RS) < 512
Therefore, if RS = 0 and the Hold Count Cut-In point is 64,
the largest value of Hold Counts you can choose is 4.
4 * (64 - 1) + (225 - 0) = 477
The GSEL bit determines which of the two gauges the rest
of the RMPSELR bits are applied to. A GSEL bit set to logic
1 will apply the RMPSELR data to Gauge 1 and, Logic 0 to
Gauge 0, respectively. Configuring both gauges requires two
writes to this register.
The bits in
Table 15
are
write-only
.
GSEL 12 (D12) — Gauge Select bit. The value of this bit
determines the gauge for which the settings apply (refer to
page
17
):
1 = Gauge 1
0 = Gauge 0
GSEL 11 (D11) — This bit must be transmitted as Logic 0
for valid commands.
HCP2 : HPC0 (D10 D8) — Hold Count Cut-in Point
variable. These bits determine HCP, which is then multiplied
by 8, and added to the RS number, to determine the actual
Hold Count Cut-In Step value. The values of HCP range from
1 to 8 as shown in
Table 16
. The default value is 2.
.
Table 16. First Hold Count Velocity Position
HC3 : HC0 (D7 : D4) — These bits determine the number of
Hold Counts that will be applied to the steps that are
determined by the HCP2:HCP0 and RS3:RS0 bits. The HC
values range from 0 to 15 and are shown in
Table 17
. The
default value is 5.
RS3 : RS0 (D3 D0) — These bits determine the number of
velocity steps that are truncated from the Velocity Position
ramp. The values range from 0 to 15 and are shown in
Table 18
. The default value is 0.
