Mode 10: SPI Mode with the Outputs PD5 (T2O1), PD6 (T2O2) and PD7 (SDIN) Pins
The Timer2/Counter2 can be supplied with internal/external clocks. Mode 10 uses three modula-
tor I/O pins (SO --> T2O1, SCLK --> T2O2 and SI --> SDIN). The timer output clock (CLK
T2) can
be used to supply the SSI with shift clock. The SPI mode of the timer allows a SSI synchronous
data transfer between the ATA6289 and peripheral devices. The data is always shifted from
Master (SSI) to Slave on the Serial data Output line (SO) and from Slave to Master (SSI) on the
Serial data Input line (SI), synchronized to either the rising or falling edge of the shift clock output
line (SCLK). The Serial data is organized in 8-bit telegrams which are shifted with the most sig-
nificant bit (MSB) first on the serial data output line (SO). Figure 3-45 shows an example of a
three-wire synchronous serial data transfer.
