TYPICAL APPLICATIONS
INTRODUCTION
15
PECCR
(f) Send null command to see if gauges have moved
- Bits PE12
Table 7
(page
14
),
Table 15
(page
19
)
(g) Check SO to see if Gauge 0 (Gauge 1) moved
- Bit MOV0 (MOV1) logic [1] If so, Gauge 0 (Gauge 1) moved another microstep. Keep
track of movement. If 12 steps are finished, and both gauges are at a static position, then
RTZ. Otherwise repeat steps (a) and (b)
- Bit CMD0 (OD10) (CMD1 (OD1)) could also be monitored to determine that the pointer is
static
16
RTZ
(a) Return one gauge at a time to the zero stop using RTZ command
- Bit RZ0 selects the gauge
- Bit RZ1 is used to enable or disable an RTZ
- Bit RZ2 is used to select the direction (along with PE7)
Table 7
(page
14
),
Table 11
(page
16
),
Table 16
(page
20
)
(b) Select the RTZ accumulator bits clocking out on the SO bits using bits PE11:PE10. These
will be used if characterizing the RTZ
17
PECCR
(a) Check the status of the RTZ by sending the null command to monitor SO bit RTZ0
- Bit PE12 is the null command
Table 7
(page
14
),
Table 15
(page
19
)
(b) Is RTZ0 logic [0] If not, Gauge 0 still returning and null command should be resent
18
RTZ
(c) Return the other gauge to the zero stop. If the second gauge is driving a different pointer
than the first, a new RTZCR command may be required to change the Full Step time

PECCR
(a) Check the status of the RTZ by sending the null command to monitor SO bit RTZ1
- Bit PE12 is the null command
Table 7
(page
14
),
Table 15
(page
19
)
(b) Is RTZ1 logic [0] If not, Gauge 1 still returning and null command should be resent
Table 11
(page
16
)
20
PECCR
(a) Disable both gauges and go to standby
- Bit PE0:PE1 are used to disable the gauges
Table 7
(page

)
(b) Put the device to sleep
