Table 5-39. eUSCI (UART Mode) Clock Frequency PARAMETER TEST CONDITIONS VCORE VCC MIN MAX UNIT feUSCI eUSCI input clock frequency Internal: SMCLK, External: UCLK, Duty cycle = 50% ±10% 1.2 V 12 MHz 1.4 V 24 fBITCLK BITCLK clock frequency (equals baud rate in MBaud) 1.2 V 5 MHz 1.4 V 7 Table 5-40 lists the characteristics of the eUSCI in UART mode. (1) Pulses on the UART receive input (UCxRX) shorter than the UART receive deglitch time are suppressed. Thus the selected deglitch time can limit the maximum useable baud rate. To ensure that pulses are correctly recognized, their duration must exceed the maximum specification of the deglitch time.
