(0x57), M_THS_Z_MSB (0x58), M_THS_Z_LSB (0x59) registers
The M_THS_X/Y/Z registers contain the unsigned 15-bit magnetic thresholds used by the magnetic-threshold function. Each
register has a resolution of 0.1
register has a resolution of 0.1
μT/LSB. The thresholds are evaluated after the magnetic data has been adjusted by the offset
value stored in the M_OFF_X/Y/Z registers when M_CTRL_REG3[m_raw] = 0.

Description
m_ths_dbcntm
The m_ths_dbcntm bit configures the way in which the debounce counter is reset when the magnetic event of interest is
momentarily not true.
When m_ths_dbcntm = 1, the debounce counter is cleared to 0 whenever the magnetic event of interest is no longer true.
When m_ths_dbcntm = 0, the debounce counter is decremented by 1 whenever the magnetic event of interest is no
longer true.
momentarily not true.
When m_ths_dbcntm = 1, the debounce counter is cleared to 0 whenever the magnetic event of interest is no longer true.
When m_ths_dbcntm = 0, the debounce counter is decremented by 1 whenever the magnetic event of interest is no
longer true.
m_ths_x[14:8]
Upper 7 bits of the 15-bit unsigned X-axis magnetic threshold.
