Table 6-3 Resistors and Capacitors
Resistors and Capacitors
R172-R195ADC RC input filter resistors: Series resistors which can be used to create an RC filter on the ADC's input.
C128-C151ADC RC input filter capacitors: Optional capacitors, not populated by default, for the RC filter of the ADC input.
Table 6-4 Switches
Switches
S1 Isolated emulation and UART communication enable switches:
S1 Position 1 – USB JTAG Enable:
  • ON (default)– All 4 JTAG signals from the embedded XDS110 emulation logic are passed across the isolation barrier and connected to the MCU. This setting is valid when the MCU is being debugged or programmed using the embedded XDS110 emulator.
  • OFF – The 4 JTAG signals from the embedded XDS110 emulation logic are passed across the isolation barrier and are NOT connected to the MCU. This setting is valid when the device boots from FLASH, boots from a peripheral directly, or when an external JTAG emulator is used.
S1 Position 2 – USB UART communication enable:
  • ON (default)– The C2000 MCU GPIO28 is connected to the embedded XDS110. This allows UART communication to a computer COM port. However in this position, GPIO28 and GPIO29 are reserved for COM port use. The corresponding pins on the 180-pin controlCARD connector cannot be used for another function.
  • OFF – The C2000 MCU GPIO28 is NOT connected to the embedded XDS110. The corresponding pins on the 180-pin controlCARD connector can be used for another function.
S2
Note: Watchdog output is disabled (default). To enable watchdog functionality over S2, populate R55.

Enable/Disable watchdog Timer & adjustable programmable delay:

S3 Boot Mode Switch: Controls the Boot Options of the F28P65x device, see Table 6-6. For a full description, see the device specific data sheet.
S4 Reset switch: Switch connected to the XRSn line of the F28P65x device. Pressing this button pulls the device reset low.
S5

ADC VREFHI Control Switch for ADC modules B & C:

S5 Position 1 (lower switch) - VREFHI Control Switch for ADC module C:

  • LEFT position - ADC-C is configured to use internal voltage reference can be selected to be 0V to 3.3V or 0V to 2.5V.
  • RIGHT (default) position - ADC-C is configured to use an external voltage reference.

S5 Position 2 (upper switch) - VREFHI Control Switch for ADC module B:

  • LEFT position - ADC-B is configured to use internal voltage reference can be selected to be 0V to 3.3V or 0V to 2.5V.
  • RIGHT (default) position - ADC-B is configured to use an external voltage reference.
S6

ADC VREFHI Control Switch for ADC modules A and selection of external voltage reference:

S6 Position 1 (lower switch) - VREFHI Control Switch for ADC module A:

  • LEFT position - ADC-A is configured to use internal voltage reference can be selected to be 0V to 3.3V or 0V to 2.5V.
CAUTION:

The reference pins, VREFHIA to VREFHIC and VREFLOA to VREFLOC, can be used to supply an external voltage reference to the associated ADCs. VREFHIA can also be used to supply the voltage reference to DAC A, and VREFHIB can be used to supply the voltage reference to DAC C. An internal voltage reference is available and connects to VREFHIA. To use the internal voltage reference on ADC B, ADC C or DAC C, connect VREFHIA to VREFHIB and/or VREFHIC externally.

  • RIGHT (default) position - ADC-A is configured to use an external voltage reference.

S6 Position 2 (upper switch) - External VREFHI Control Switch for all ADC modules:

  • LEFT position - External voltage reference is set to use full-scale range of ADC with 0-3.3 V, but the ADC has reduced accuracy/precision.

  • RIGHT (default) position - External voltage reference is set to use an onboard precision 3V voltage reference.
