Notes:  Pins of port 2, P32 to P35, P50 and P51, and P81 and P83 are 5-V tolerant. 
  1.  When the A/D and D/A converters are not used, the AV
CC
, V
ref
, and AV
SS
 pins should not 
be open. Connect the AV
CC
 and V
ref
 pins to V
CC
, and the AV
SS
 pin to V
SS
. 
  2.  When used as IRQ, TIOC, TCLK, TMRI, SCL, or SDA. 
  3.  When used as other than IRQ, TIOC, TCLK, TMRI, SCL, or SDA. 
  4.  When used as SCL or SDA. 
  5.  When used as SSO, SSI, SSCK, SCS, WAIT, ADTRG1 or DREQ. 
  6.  When used as other than SSO, SSI, SSCK, SCS, WAIT, ADTRG1 or DREQ.
