Table 1. Triple-timer Counter Interface
Symbol Description Min Max Units
FTTCX_REF_CLK Triple-timer counter input clock frequency (TTCx_REF_CLK) 1 See Note 1 MHz
FTTCX_IO_REF_CLKX Triple-timer counter MIO-EMIO input clock frequency (TTCx_IO_REF_CLKx) 2 50 3 MHz
TTTCICLK Triple-timer counter MIO-EMIO input clock High pulse width 2/FTTCX_IO_REF_CLKX 2 μs
Triple-timer counter MIO-EMIO input clock Low pulse width 2/FTTCX_IO_REF_CLKX 2 μs
FTTCICLK Triple-timer counter output clock frequency FTTCX_REF_CLK/2 1 MHz
  FTTCX_IO_REF_CLKX/2 2 MHz
TTTCOCLK Triple-timer counter output clock period 2/FTTCX_REF_CLK 1 μs
2/FTTCX_IO_REF_CLKX 2 μs
  1. TTCx_REF_CLK source is used. TTCx_REF_CLK source can be the REF_CLK (FREFCLK), LPD_LSBUS_CLK (FLPD_LSBUS_CLK), or the RPU_REF_CLK (FRPUMAX).
  2. TTCx_IO_REF_CLKx source is used. TTCx_IO_REF_CLKx source can be MIO or EMIO.
  3. The maximum FTTCx_IO_REF_CLKx is the lesser of the specified maximum FTTCX_IO_REF_CLKX or FTTCX_REF_CLK/2.
