Magnetic-threshold interrupt source register.

This register keeps track of the magnetic threshold event which is triggering (or has triggered, when M_THS_CFG[m_ths_ele] 
= 1) the event flag. In particular, if M_THS_SRC[m_ths_ea] is set to a logic ‘1’ then the logical combination of magnetic-event 
flags specified in M_THS_CFG is true.

m_ths_ea

Event-active flag. 
0: No event flag has been asserted
1: One or more event flag(s) has been asserted.

m_ths_zhe

Z-high event flag. 
0: No event detected
1: Z-high event has been detected 
This bit always reads zero if the m_ths_zefe control bit is set to zero

m_ths_zhp

Z-high event polarity flag. 
0: Z event detected was positive polarity
1: Z event detected was negative polarity
This bit always reads zero if the m_ths_zefe control bit is set to zero

m_ths_yhe

Y-high event flag. 
0: No event detected
1: Y-high event has been detected
This bit always reads zero if the m_ths_yefe control bit is set to zero

m_ths_yhp

Y-high event polarity flag. 
0: Y event detected was positive polarity
1: Y event detected was negative polarity
This bit always reads zero if the m_ths_yefe control bit is set to zero

m_ths_xhe

X-high event flag. 
0: No event detected
1: X-high event has been detected 
This bit always reads zero if the m_ths_xefe control bit is set to zero

m_ths_xhp

X-high event polarity flag. 
0: X event detected was positive polarity
1: X event detected was negative polarity. 
This bit always reads zero if the m_ths_xefe control bit is set to zero
