Name
Base
Default
CURR2
2-wire serial
00h
Offset: 1Bh-4
Current Sink 2 Register
This is an extended register and needs to be enabled by writing 100b to Reg. 1Ch first.
This register is reset at a VDD27-POR or XRES input.

Name
Base
Default
PMU_Enable
2-wire serial
00h
Offset: 1Ch
PMU_Enable Register
Selects the extended register on address 17h to 1Bh and enables writing to these PMU register. It also
sets the ADC10 multiplexer to measure various regulator voltages
This register is reset at a VDD27-POR or XRES input.
Bit

Bit Description
7:4
DC_TEST_MUX
<3:0>
0000
R/W
Allows multiplexing internal and external supply voltages to one DC test
node which can be further multiplexed to the ADC10. The accuracy is 5mV/
LSB (see reg. 2Eh)
0x0: open
0x1: PVDD1
0x2: PVDD2
0x3: PVDD3

0x8: CVDD3
0x9-0xF: n/a
3
PMU_GATE
0
R/W
Enables all settings made in registers 17h to 1Bh at once. If this bit is set,
changes are activated as soon as they are written to the related register.
0: no change
1: change at once
2:0
PMU_ENABLE
<2:0>
000
R/W
Selects extended registers 17h to 1Bh for the next read or write. This register
has to be set before every read or write even if the selection is not changing.
0: 19h-0 selected
1: 17h-1 to 1Bh-1 selected
2: 17h-2 to 1Bh-2 selected
...
7: 17h-7 to 1Bh-7 selected
