Section 7: Simple Input/Output Port
MC68HC05C5 Specification Rev. 1.2
While the SIOP is enabled, PB5 can not be used as a standard output since that pin is
coupled to the last stage of the serial shift register. If CPOL is set, the first falling edge of
SCK will shift the first data bit out to the output pin. If CPOL is clear, the first data bit will
be on the SDO pin waiting for the transmission.
7.1.3
SDI
The SDI pin becomes an input as soon as the SIOP is enabled. New data may be
presented to the SDI pin on the falling edge of SCK. Valid data must be present at least
t
S
before the rising edge of the clock and remain valid for t
H
after the
edge.
