1. This pin can be used as programmable I/O port.
2. Do not set both the TE and RE bits to 1 in 4-wire bus (bidirectional) communication mode.
Clock synchronous serial I/O with chip select switches functions of the I/O pin in each communication mode
according to the setting of the MSS bit in the SSCRH register and the RE and TE bits in the SSER register.
Table 16.4 shows the Association between Communication Modes and I/O Pins.
