8.3 MIS34x & MIS43x Registers
8.3.57 S_Time
Description: This value selects the time in milliseconds between samples of the registers selected in
registers 112-115.
8.3.58 S_Control
Description: This value controls the sample system. It can assume three different values:
A value of zero is set by the firmware after all sampling has completed.
A value of one will initialize the sample system.
A value of two will start a new sample sequence and set this register to zero at comple-
tion.
The sampled values are read back using the command hex 53 SMC75_READSAMPLE.
8.3.59 Buf_Size
Description: This read-only register contains the maximum length of the sample buffers used to sam-
ple the registers selected in registers 112-115.
Register 116 should never be set to a value higher than the value in this register.
8.3.60 Index_Offset
Description: This register can be selected to receive the absolute value of the internal encoder where
the Zero search/home position was found during Zero Search. This is selected by bit 0,
Use Index, in register 122. It requires that the internal encoder option is installed.
8.3.61 Home_Bits
Description: Bit 0: Search for index
Bit 1: Change direction on limit.
Bit 2: Search for opposite side of sensor
Bit 3: (Use Limit switch as sensor) - Not available in MIS34x and MIS43x.
Bit 4: Ignore switch (Used for searching only for index)
Contains configuration bits, that define how Zero search should be carried out.
