FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
CONFIG MODE:
Configuration mode is the mode in which the IC is programmed or configured by the external digital subsystem via the serial
interface (i.e., MOSI, MISO, SCLK, CE).

Bit Description
Reserved for Freescale test. Set to [10].
Data for various calibration registers.
Routes A and B output of analog encoder interface to AN0 and AN1, respectively. Used only for user
development and verification. Do not use in normal operation.
Determines the calibration register, as identified in Table 14 below, the calibration data in the cal[4:0] (Bits
13 –9) bits is latched in.
Determines the number of SCLK edges used to filter the DENCA and DENCB signals coming from the Digital
Signal Generation stage of the analog encoder interface. This digital filter filters the DENCA and DENCB
signals made available to the serial output frame.
Determines if Motor Driver C operates in DC motor or step motor mode. Implicitly determines whether
HSOUTx or LSOUTx are available. In DC motor mode, LSOUTx are available; in step motor mode, HSOUTx
are available.
Determines how many SCLK edges are required for conversion. This allows the use of a faster SCLK but still
maintains A/D conversion accuracy.
When asserted, causes the 34921 to enter a power-down state, and minimize power consumption.
Causes the next output frame sent to the host to contain internal information from the 34921.
The input frame can be either a configuration frame or a normal frame. Bit 0 determines the type of frame being
received. Bit 0 = 1 is a configuration mode input frame.
Notes
32. All defaults = 0 at power up.
