Bit 7 is reserved. It is fixed at 1, and cannot be modified.
• Modes 1 to 4 (Expanded Modes)
Port 6 Data Register (P6DR): P6DR is an 8-bit readable/writable register that stores output data
for port 6. When port 6 functions as an output port, the value of this register is output. For bit 7, a
value of 1 is returned if the bit is read while the PSTOP bit in MSTCRH is cleared to 0, and the
P6 7 pin logic level is returned if the bit is read while the PSTOP bit is set to 1. Bit 7 cannot be
modified. For bits 6 to 0, the pin logic level is returned if the bit is read while the corresponding
bit in P6DDR is cleared to 0, and the P6DR value is returned if the bit is read while the
corresponding bit in P6DDR is set to 1.
P6DR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
