MCLK, CPUCLK, ULPCLK frequency with 0 flash wait states 24
fULPCLK(PD0 bus clock) ULPCLK frequency 40 MHz
Note:
  • The total current of I/O must be less than the maximum value of IVDD.
  • HDIO, HSIO and ODIO are patched in a fixed pin, see to the device data sheet.

SDIO and HSIO are able to sink or source a maximum current of 6 mA (typical), which is sufficient to drive a typical LED. For larger current loading, use HDIO (maximum current of 20 mA (typical)). However, the total combined current must be less than IVDD (80 mA typical).
