Device HW Driver Register
Bits(s)
Type (R/W)
Description
This register contains the manufacturer and
HW identification
7:0
R
device ID(1) (value to be specified by the
manufacturer)
(1)
The manufacturer ID part of this data shall remain unchanged when the HW revision ID is updated. The manufacturer ID shall uniquely
identify the manufacturer. The manufacturer ID is encoded on the MSB nibble.

0
R
counter has expired
'0' SDN signal at GND
'1' SDN signal at V_I/O level
SDN interrupt status
'0' No interrupt
SDN Interrupt(1)
1
R
'1' Interrupt occurred, (the read operation will
automatically clear this bit)
'0' Battery present
Battery Status
2
R
'1' Battery not present, i.e. debounce counter
expired
Battery removal interrupt status
'0' No interrupt
Battery Removal Interrupt
3
R
'1' Interrupt occurred, (the read operation will
automatically clear this bit)
Status of SIM1 interface
'00' Powered down with pull-downs activated
SIM1 Interface Status [1:0]
5:4(2)
R
'01' Isolated with pull-downs deactivated
'10' Powered with pull downs activated
'11' Active with pull downs deactivated
Status of SIM2 interface
'00' Powered down with pull-downs activated
SIM2 Interface Status [1:0]
7:6(2)
R
'01' Isolated with pull-downs deactivated
'10' Powered with pull downs activated
'11' Active with pull downs deactivated
(1)
The SDN status bit indicates the state of the SDN signal at the input when the debounce counter expired, i.e. when the SDN interrupt bit
is set.
(2)
The content of bits 5:4 and 7:6 reflects the value written to the state bits in the SIM Interface control register 3:2 and 7:6 respectively
and the setting of the regulator bits in the SIM interface control register 0 and 4 respectively.
