Section 18 Serial Communication Interface 4 (SCI4)
The serial communication interface 4 (SCI4) can handle clock synchronous serial communication
with the 8-bit buffer. The SCI4 is supported only by the F-ZTAT version. When the on-chip
emulator debugger etc. is used, the SCK4, SI4, and SO4 pins of the SCI4 are used by the system,
and the SCI4 is not available for the user.
18.1 Features
Eight internal clocks (φ/1024, φ/256, φ/64, φ/32, φ/16, φ/8, φ/4, φ/2) or external clock can be
selected as a clock source.
Receive error detection: Overrun errors detected
Four interrupt sources
Transmit-end, transmit-data-empty, receive-data-full, and overrun error
Full-duplex communication capability
Buffering is used in both the transmitter and the receiver, enabling continuous transmission
and continuous reception of serial data.
When the on-chip emulator debugger etc. is not used, the SCI4 is available for the user.
Use of module standby mode enables this module to be placed in standby mode independently
when it is not in use. (For details, refer to section 6.4, Module Standby Function.)
