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).

In handshake output mode, DDRC bits select the 3-stated output
option (DDCx = 1).
