33.13 DMA Timer Module AC Timing Specifications

Table 33-21lists timer module AC timings.

Table 33-21. Timer Module AC Timing Specifications

Name	Characteristic 1	Min	Max	Unit
T1	DTIN0 / DTIN1 / DTIN2 / DTIN3 cycle time	3	—	tCYC
T2	DTIN0 / DTIN1 / DTIN2 / DTIN3 pulse width	1	—	tCYC

1All timing references to CLKOUT are given to its rising edge when bit 3 of the SDRAM control register is 0.
