Product data sheet
Standard digital output
If the standard digital output mode is configured, output data can be read with the serial
interface.
enclosed by a HIGH-to-LOW and LOW-to-HIGH transition of CS.
DATA are clocked out at the falling edge of CLK and should be evaluated at the rising
edge. The output data consist of 3 bytes (24 bits). The first two data bytes contain an error
flag and 13 bits of angle information. The last data byte contains the measured
temperature as 7-bit value. Every byte features a parity bit (odd parity).
The data transmission can be interrupted at any time by deactivating CS. If, for instance,
the temperature information is not desired, the data transfer can be finished by
deactivating CS after reading the first two data bytes.
If the error flag is 0, the 13 angle data bits contain the most significant bits of the
calculated angle. If the error flag is 1, an error condition was detected. The two least
significant angle data bits (A[1:0]) are replaced by an error code. All other angle data bits
(A[12:2]) still show the current measurement value. Depending on the special error case,
the measurement values are reliable or not. Error codes are described in
The output driver of the DATA pin is slew-rate limited. The rise and fall times of the DATA
output can be programmed with the SL bit (ctrl EEPROM constant); see
Complementary digital output
In complementary digital output mode the data transmitted is identical to the output data in
standard digital output mode except that the angle and temperature information data bits
are logically inverted. The error flag and the error code in bits A[1:0] when the error flag is
set are coded as in case of standard digital output. The parity bits also use odd parity as
standard digital output mode.
