4.2 Jumpers
The following table shows the installed jumpers.
Table 2. Jumpers
Jumper Title Shunt Location Description
JP1 EXT_THERM Installed Jumper to connect thermistor (R2) to pin TS
(J13)
JP2 INT PULLUP Between pin 1 and pin 2 Jumper to select pullup voltage for INT pin
(L10). Pin 1 and pin 2 shorted INT pulled up
to 2V2. If pin 2 and 3 are shorted /INT is
pulled up to LDO8
JP3 I2C_PU Not Installed Jumper to select pullup voltage for SCLK
(H4) and SDAT (J2). Position 1 and position
2 shorted for 2V2 pullup; position 2 and
position 3 shorted for pullup to RTC_OUT
(H1).
JP4 32KOUT-PWR Installed Jumper to connect V32K (D7) to RTC_OUT
(H10)
JP5 32K-CLOAD Not Installed Jumper to connect 50-pF capacitor to
OUT32K (C7)
JP6 RESUME Not Installed Jumper to connect RESUME (B2) to pin P2
of the I2C port expander (U2)
JP7 SEQCTRL Between pin 1 and pin 2 Jumper to connect SEQCTRL (B3) to either
2V2 or pin P3 of the I2C port expander U2
JP8 SYNCEN Between pin 1 and pin 2 Jumper to connect SYNCEN (E10) to either
2V2 or pin P4 of the I2C port expander U2
JP9 SM1EN Between pin 1 and pin 2 Jumper to connect SM1EN (E11) to either
2V2 or pin P5 of the I2C port expander U2
JP10 SM0EN Not Installed Jumper to connect SM0EN (F10) to either
2V2 or pin P5 of the I2C port expander U2
JP11 VIN_LDO01 Between pin 2 and pin 3 Jumper to select VIN or SM2 as input to
LDO0 and LDO1
