1.18.2 SIO Normal Operation
An internal clock or an external clock can be selected
as the synchronous clock. When the internal clock is
chosen, dividers are built in to provide eight different
clock selections. The start of a transfer is initiated by
a write signal to the SIO shift register (address
002A
16
). The SRDY signal then drops active low. On
the negative edge of the transfer clock SRDY returns
high and the data is transmitted out the STXD pin.
Data is latched in from the SRXD pin on the rising
edge of the transfer clock. If an internal clock is se-
lected, the STXD pin enters a high-impedance state
after an 8-bit transfer is completed. If an external
clock is selected, the contents of the serial I/O regis-
ter continue to be shifted while the send/receive clock
is being input. Therefore, the clock needs to be con-
trolled by the external source. Also there is no STXD
high-impedance function after data is transferred.
Regardless of whether an internal or external clock is
selected, after an 8-bit transfer, the interrupt request
bit is set. Figure 1.39 shows the timing for the serial I/
O with the LSB-first option selected.

Note:
When the internal clock is selected, the TxD pin goes into high-
impedance after the data is transferred.
