⎯:  Not used as the SSU pin (can be used as an I/O port). 
Notes:  See tables 19.4 to 19.6. 
  1.  Do not set BIDE to 1 when SSUMS = 1 in SSU. 
  2.  Do not specify that TE = RE = 1 when operating with BIDE = 1 (bidirectional mode). 
•  P13/TEND1/PO11/TIOCD0/TCLKB 
The pin function is switched as shown below according to the combination of bit TEE1 in 
DMATCR of the DMAC, TPU channel 0 settings (by bits MD3 to MD0 in TMDR_0, bits 
IOD3 to IOD0 in TIORL_0, and bits CCLR2 to CCLR0 in TCR_0), bits TPSC2 to TPSC0 in 
TCR_0 to TCR_2, bit NDER11 in NDERH of the PPG, and bit P13DDR.

Notes:  1.  TIOCD0 input when MD3 to MD0 = B'0000 and IOD3 to IOD0 = B'10xx. 
  2.  TCLKB input when the setting for any of TCR_0 to TCR_2 is TPSC2 to TPSC0 = B'101. 
TCLKB input when phase counting mode is set for channels 1 and 5.
