PORTCL is used in the handshake clearing mechanism. When an active edge occurs on the STRA pin,
port C data is latched into the PORTCL register. Reads of this register return the last value latched into
PORTCL and clear STAF flag (following a read of PIOC with STAF set).
DDRC[7:0] — Port C Data Direction Bits
6.5 Port D
In all modes, port D bits [5:0] can be used either for general-purpose I/O or with the serial communications
interface (SCI) and serial peripheral interface (SPI) subsystems. During reset, port D pins PD[5:0] are
configured as high-impedance inputs (DDRD bits cleared).
Bits [7:6] — Unimplemented
DDRD[5:0] — Port D Data Direction Bits

Parallel Input/Output (I/O) Ports
In the 3-state variation of output handshake mode, clear the corresponding DDRC bits. Refer to
10-13. 3-State Variation of Output Handshake Timing Diagram (STRA Enables Output
Always read 0
When DDRD bit 5 is 1 and MSTR = 1 in SPCR, PD5/SS is a general-purpose output and mode fault
logic is disabled.
