DETAILS OF REGISTERS
Table 21. PE/PMU Enable (ADDR[4:0] = 0x0C)
Bit
Name
Description
DATA[2]
PMU enable
0 = disable PMU force output and clamps, place PMU in MV mode
1 = enable PMU force output
When set to 0, the PMU state bits are ignored, except for PMU sense path (Data[7])
DATA[1]
Force VT
0 = normal driver operation
1 = force driver to VT
See Table 29 for complete functionality of this bit
DATA[0]
PE disable
0 = enable driver functions
1 = disable driver (low leakage)
See Table 29 for complete functionality of this bit
Table 22. Channel State (ADDR[4:0] = 0x0D)
Bit
Name
Description
DATA[2]
HV mode select
0 = HV driver in low impedance.
1 = enable HV driver.
This bit affects Channel 0 only. Ensure that the Channel 0 bit in SPI write is active.
Channel 1 bit in SPI write is don’t care.
DATA[1]
Load enable
0 = disable load.
1 = enable load.
See Table 29 for complete functionality of this bit.
DATA[0]
Driver high-Z or VT
0 = enable Driver high-Z function.
1 = enable Driver VTERM function.
See Table 29 for complete functionality of this bit.
Table 23. PMU State (ADDR[4:0] = 0x0E)1, 2
Bit
Name
Description
DATA[9:8]
PMU input selection
00 = VDUTGND (calibrated for 0.0 V voltage reference)
01 = 2.5 V + VDUTGND (calibrated for 0.0 A current reference)
1X = PMUDAC
DATA[7]
PMU sense path
0 = internal sense
1 = external sense
DATA[6]
Reserved
DATA[5]
PMU clamp enable
0 = disable clamps
1 = enable clamps
DATA[4]
PMU measure voltage or current
0 = measure voltage mode
1 = measure current mode
DATA[3]
PMU force voltage or current
0 = force voltage mode
1 = force current mode
DATA[2:0]
PMU range
0XX = 2 μA range
100 = 20 μA range
101 = 200 μA range
110 = 2 mA range
111 = 32 mA range
1 Note that when ADDR[4:0] = 0x0C, the PMU enable bit (DATA[2]) = 0, PMU force outputs and clamps are disabled, and the PMU is placed into measure voltage mode.
PMU State DATA[9:8] and DATA[6:0] are ignored, and only the DATA[7] PMU sense path is valid.
2 X = don’t care.
