DATA UART Interface
The RZ/G1H Qseven SOM supports two UART interface on Qseven Edge connector for Data UART interface and Debug
UART interface. RZ/G1H
CPU’s SCIF
B2 controller is used for Data UART interface with hardware flow control for request
to send and clear to send signals on Qseven Edge connector.
The RZ/G1H
CPU’s SCIFB
2 supports serial communication interface incorporating 256-byte transmit/receive FIFOs that
handles asynchronous communication. Serial data communications can be carried out with standard asynchronous
communications chips such as a Universal Asynchronous Receiver/Transmitter. It has On-chip baud rate generator
that allows any bit rate to be selected. Also it supports multi-byte DMA transfers.
For more details, refer Qseven Edge connector pins 171, 172, 177 & 178 for Data UART interface on
2.6.12
CAN Interface
The RZ/G1H Qseven SOM supports one CAN interface on Qseven Edge connector along with one more CAN interface
on Expansion connector2. RZ/G1H
CPU’s
CAN module supports two channels in which CAN1 channel is connected to
Qseven Edge connector.
The RZ/G1H
CPU’s
CAN module complies with the ISO11898-1 Specifications and supports programmable bit rate up
to 1 Mbps with both formats of messages namely the standard identifier (11 bits) and extended ID (29 bits). It also
supports 64 mailboxes in two selectable (Normal and FIFO) mailbox mode. To connect external CAN module to this
bus, it is necessary to add transceiver in between.
For more details, refer Qseven Edge connector pins 129 & 130 on
2.6.13
SPI Interface
The RZ/G1H Qseven SOM supports one SPI interface with two chip selects on Qseven Edge connector along with one
more SPI interface on Expansion conenctor2. RZ/G1H
CPU’s
MSIOF0 is used for SPI interface which supports full-duplex
synchronous four-wire serial interface with DMA.
The RZ/G1H
CPU’s
MSIOF0 supports serial formats IIS, SPI (master and slave modes) at max speed of 26Mbps. It
supports 32bit x 64 stages for transmit FIFOs & 32bit × 256 stages for receive FIFOs and allows MSB first or LSB first
selectable for data transmission and reception.
For more details, refer Qseven Edge connector pins 199 to 203 on
