As regards the access type to a particular register the following four types have been implemented:

r/w

normal read/write

read only

r/rst

read only, clear by read

w/pulse

writing to such type of registers causes a partial reset of certain IC functions which

correspond to the assigned bit of the write accessed register; reading is possible but will

return no useful information

In order to illustrate for instance the w/pulse type a write access to status register MON_RST_LOCK_WURQ shall

be explained. The bits of this register are assigned to

 the power fail event (bit 4) and

 the IO-Link specific wake-up request event (bit 3) and

 the COM/AUX driver over-current event (bit 2 and 1) and

 the over-temperature event (bit 0).

Writing the value 0x08 (MON_RST_WURQ = 1) to the register would cause a reset of the previously detected and

stored wake-up request. In doing so the to the IC interconnected µC acknowledges the occurred wake-up request

thus the IC is ready to detect the next wake-up request.
