Table 1. Triple-timer Counter Interface
Symbol	Description	Min	Max	Units
F_{TTCX_REF_CLK}	Triple-timer counter input clock frequency (TTCx_REF_CLK)¹	–	See Note 1	MHz
F_{TTCX_IO_REF_CLKX}	Triple-timer counter MIO-EMIO input clock frequency (TTCx_IO_REF_CLKx)²	–	50³	MHz
T_TTCICLK	Triple-timer counter MIO-EMIO input clock High pulse width	2/F_{TTCX_IO_REF_CLKX} ²	–	μs
T_TTCICLK	Triple-timer counter MIO-EMIO input clock Low pulse width	2/F_{TTCX_IO_REF_CLKX} ²	–	μs
F_TTCICLK	Triple-timer counter output clock frequency	–	F_{TTCX_REF_CLK}/2¹	MHz
F_TTCICLK	Triple-timer counter output clock frequency		F_{TTCX_IO_REF_CLKX}/2²	MHz
T_TTCOCLK	Triple-timer counter output clock period	2/F_{TTCX_REF_CLK} ¹	–	μs
T_TTCOCLK	Triple-timer counter output clock period	2/F_{TTCX_IO_REF_CLKX} ²	–	μs
TTCx_REF_CLK source is used. TTCx_REF_CLK source can be the REF_CLK (F_REFCLK), LPD_LSBUS_CLK (F_{LPD_LSBUS_CLK}), or the RPU_REF_CLK (F_RPUMAX). TTCx_IO_REF_CLKx source is used. TTCx_IO_REF_CLKx source can be MIO or EMIO. The maximum F_{TTCx_IO_REF_CLKx} is the lesser of the specified maximum F_{TTCX_IO_REF_CLKX} or F_{TTCX_REF_CLK}/2.
