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

TMS320VC5502

Fixed-Point Digital Signal Processor

SPRS166H – APRIL 2001 – REVISED NOVEMBER 2004

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

NO.

UNIT

MIN

MAX

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

(1)

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

CLKOUT.

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

(1)

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

CLKOUT.
