Alternate Functions of Port B
The Port B pins with alternate functions are shown in
Table 4-32.
Read/Write
Initial Value
• Bit 4 – PUD: Pull-up Disable
Port Pin
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn and
PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0b01). See
“Configuring the Pin” on page 88
