Table 5-51. GPIO Implementation (Sheet 2 of 2)
NOTES:
1. All GPIOs default to their alternate function.
2. All inputs are sticky. The status bit remains set as long as the input was asserted for 2 clocks. GPIs are
3. GPIO[0:7] are 5 V tolerant, and all GPIs can be routed to cause an SCI or SMI#.
4. If GPIO_USE_SEL bit 1 is set to 1 and GEN_CNT bit 25 is also set to 1 then REQ/GNT[5]# is enabled. See
