10.2.4
SCI1 can generate an interrupt at the end of a data transfer.
When an SCI1 transfer is complete, bit IRRS1 in interrupt request register 1 (IRR1) is set to 1.
SCI1 interrupt requests can be enabled or disabled by bit IENS1 of interrupt enable register 1
(IENR1).
For further details, see 3.3, Interrupts.
10.2.5
When an external clock is input at pin SCK
source bit STF in SCSR1 must first be set to 1 to start data transfer before inputting the external
clock.

10.3.1
Serial communication interface 2 (SCI2) has a 32-bit data buffer for synchronous serial transfer of
up to 32 bytes of data in one operation.
Features
Features of SCI are listed below.
234
Automatic transfer of up to 32 bytes of data
Choice of seven internal clock sources ( /256, /64, /32, /16, /8, /4, /2) or an external
clock
Interrupts requested at completion of transfer or when an error occurs
Gaps of 56, 24, or 8 internal clock cycles can be inserted between successive bytes of
transferred data.
Transfer can be started by chip select input.
A strobe pulse can be output for each byte transferred.
