MSP430F530x Demo - Internal LDO powering device VCC and PortU

Description: This example code shows the device can be automatically powered up by the internal LDO when sufficicnt is present at the LDOI pin and how the external connection between LDOO and VCC can be used to power the device VCC.

Note: 1.To power the MSP430 device VCC via the internal LDO, connect LDOO to VCC externally. If using TI target board (MSP-TS430RGC64B), jumper pin header JP4 2.Ensure current drawn by device VCC is < ILDOO spec

ACLK = 32.768kHz, MCLK = SMCLK = default DCO~1MHz

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

  • LDO-PWR module
  • GPIO Port peripheral

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

  • LDO_PWR_VECTOR.
