Signal Options, Table 3.7.

Table 3.3 UART 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.
