HMC5843
Data Output Y Registers A and B
The data output Y registers are two 8 -bit registers, data output register A and data output register B. These registers
store the measurement result from channel Y. Data output Y register A contains the MSB from the measurement result,
and data output Y register B contains the LSB from the measurement result. The value stored in these two registers is a
16-bit value in 2’s complement form, whose range is 0xF800 to 0x07FF. DYRA0 through DYRA7 and DYRB0 through
DYRB7 indicate bit locations, with DYRA and DYRB denoting the bits that are in the data output Y registers. DYRA7 and
DYRB7 denote the first bit of the data stream. The number in parenthesis indicates the default value of that bit.
In the event the ADC reading overflows or underflows for the given channel, or if there is a math overflow during the bias
measurement, this data register will contain the value -4096 in 2’s complement form. This register value will clear when
after the next valid measurement is made.
Data Output Z Registers A and B
The data output Z registers are two 8-bit registers, data output register A and data output register B. These registers
store the measurement result from channel Z. Data output Z register A contains the MSB from the measurement result,
and data output Z register B contains the LSB from the measurement result. The value stored in these two registers is a
16-bit value in 2’s complement form, whose range is 0xF800 to 0x07FF. DZRA0 through DZRA7 and DZRB0 through
DZRB7 indicate bit locations, with DZRA and DZRB denoting the bits that are in the data output Z registers. DZRA7 and
DZRB7 denote the first bit of the data stream. The number in parenthesis indicates the default value of that bit.
In the event the ADC reading overflows or underflows for the given channel, or if there is a math overflow during the bias
measurement, this data register will contain the value -4096 in 2’s complement form. This register value will clear when
after the next valid measurement is made.
