Extended I/O Serial Interfaces 0 and 1
The extended I/O serial interfaces are serial I/O interfaces that perform clock-synchronized data transfer.
The MB90520B series contain two internal extended I/O serial interface channels.
Either LSB-first or MSB-first data transmission format can be selected.
Extended I/O serial interface functions
Function
Transmission direction
Transmit and receive can be handled simultaneously. (A setting is required to select
transmit or receive.)
Transmission mode
Clock synchronous (data transfer only)
Transmission clock
Internal shift clock mode (Uses the communications prescaler output clock.)
External shift clock mode (Inputs the clock signal from SCK1 and SCK2.)
Transmission speed
When using internal shift clock :
Up to 1 MHz operation can be achieved (for a 16 MHz machine clock with the divisor
setting for the communication prescaler set to 8) . Speeds faster than 1 MHz are not
possible.
When using an external shift clock :
As a minimum of 5 machine cycles are required, when the machine clock is 16 MHz
the maximum input frequency for the external shift clock is 16 MHz
/ 5 = 3.2 MHz.
Data transmission
format
LSB-first or MSB-first, selectable
Data transfer only
Number of data bits = 8 (fixed)
Interrupt request
generation
Interrupt generated when transfer completes
EI2OS support
Supports use of the extended intelligent I/O service.
