I/O ports, POEG, GPT, AGT, KINT and ADC trigger timing (4 of 4)

GPT Conditions:

High drive output is selected in the Port Drive Capability bit in the PmnPFS register.

AGT Conditions:

Middle drive output is selected in the Port Drive Capability bit in the PmnPFS register.

Figure 2.31

Note:

tIcyc: ICLK cycle, tPcyc: PCLKB cycle, tPDcyc: GTCLK cycle, tADcyc: ADCLK cycle.

Note 1. This skew applies when the same driver I/O is used. If the I/O of the middle and high drivers is mixed, operation is not guaranteed.

Note 2. Constraints on input cycle:

When not switching the source clock: tPcyc × 2 < tACYC should be satisfied.

When switching the source clock: tPcyc × 6 < tACYC should be satisfied.

Note 3. Reference value.
