DESCRIPTION
-
GPIO17 ~ GPIO5 port pin internal pull-up resister enable
There are 13 bits for this register, the corresponding bit is set to
“1” will enable pull-up resister on IO pin.
1 = enable
0 = disable
After power on the pull-up resisters are disable.
GPIO17 ~ GPIO5 output mode enable
1 = output mode
0 = input mode
NOTE: Output mode enable bits are valid only when bit
PT5CFG12-0 is configured as general purpose I/O mode.
Each port pin can be enabled individually by setting the
corresponding control bit.
