Synchronous mode:
Full-duplex communication capability
LSB-first or MSB-first transfer can be selected
Built-in baud rate generator allows any bit rate to be selected
Choice of serial clock source: internal clock from baud rate generator or external clock from
SCK pin
Capability of transmit and receive clock output
The transmit-data-empty interrupt and receive-data-full interrupt can activate the data transfer
controller (DTC) to execute data transfer
Four interrupt sources
Serial data communication is synchronized with a clock
Serial data communication can be carried out with other chips that have a synchronous
communication function
One serial data transfer format
Data length:
Receive error detection: Overrun errors detected
The transmitter and receiver are mutually independent, enabling transmission and reception
to be executed simultaneously
Double-buffering is used in both the transmitter and the receiver, enabling continuous
transmission and continuous reception of serial data
This selection can be made regardless of the communication mode (with the exception of
7-bit data transfer in asynchronous mode) *
The P86/SCK1 and P42/SCK2 pins are CMOS type outputs
The P52/SCK0 pin is an NMOS push-pull type output in the H8S/2148 Group and
H8S/2147N, and is a CMOS output in the H8S/2144 Group (When the P52/SCK0 pin is
used as an output in the H8S/2148 Group and H8S/2147N, external pull-up resistor must be
connected in order to output high level)
Four interrupt sources (transmit-data-empty, transmit-end, receive-data-full, and receive
error) that can issue requests independently
The transmit-data-empty interrupt and receive-data-full interrupt can activate the data
transfer controller (DTC) to execute data transfer
