TIM0/TIM1/WDTOUT General-Purpose I/O Timings

Table 5−28 and Table 5−29 assume testing over recommended operating conditions (see Figure 5−30).

Table 5−28. TIM0/TIM1/WDTOUT General-Purpose I/O Timing Requirements†

NO.

MIN

MAX

UNIT

tsu(TIM0GPIO−COH)

Setup time, TIM0-GPIO input mode before CLKOUT high

T10

th(COH−TIM0GPIO)

Hold time, TIM0-GPIO input mode after CLKOUT high

T11

tsu(TIM1GPIO−COH)

Setup time, TIM1-GPIO input mode before CLKOUT high

T12

th(COH−TIM1GPIO)

Hold time, TIM1-GPIO input mode after CLKOUT high

T13

tsu(WDTGPIO−COH)

Setup time, WDTOUT-GPIO input mode before CLKOUT high

T14

th(COH−WDTGPIO)

Hold time, WDTOUT-GPIO input mode after CLKOUT high

† In this case, CLKOUT reflects SYSCLK1. The CLKOUT Selection Register (CLKOUTSR) can be programmed to select SYSCLK1 as CLKOUT.

Table 5−29. TIM0/TIM1/WDTOUT General-Purpose I/O Switching Characteristics†

NO.

PARAMETER

MIN

MAX

UNIT

td(COH−TIM0GPIO)

Delay time, CLKOUT high to TIM0-GPIO output mode

td(COH−TIM1GPIO)

Delay time, CLKOUT high to TIM1-GPIO output mode

td(COH−WDTGPIO)

Delay time, CLKOUT high to WDTOUT-GPIO output mode

† In this case, CLKOUT reflects SYSCLK1. The CLKOUT Selection Register (CLKOUTSR) can be programmed to select SYSCLK1 as CLKOUT.
