Table 3.2 Common Function pins
Table 3.3 FT1248 Interface and CBUS Group (see note 1)
Notes:
1. When used in Input Mode, the input pins are pulled to VCCIO via internal 75kΩ (approx) resistors.
These pins can be programmed to gently pull low during USB suspend (PWREN# = “1”) by setting an
option in the MTP memory.
