Abstract parallel digital bus.
The types and functions in <ctl_i2c.h> provide a high-level set of services that implement a parallel bus.
The CrossWorks Device Library provides drivers for the following devices that implement a parallel bus but are connected using I2C or SPI:
| Bus | |
| CTL_PARALLEL_BUS_t | Abstract parallel bus interface |
| ctl_bus_lock | Acquire exclusive bus lock |
| ctl_bus_lock_ex | Acquire exclusive bus lock (extended) |
| ctl_bus_unlock | Release exclusive bus lock |
| ctl_parallel_bus_initialize | Initialize structure |
| Configuration | |
| ctl_bus_set_direction | Set bus input-output direction |
| ctl_bus_set_input_mode | Set selected bus bits to input direction |
| ctl_bus_set_output_mode | Set selected bus bits to output direction |
| I/O | |
| ctl_bus_read | Read entire bus |
| ctl_bus_read_bit | Read a single bit from bus |
| ctl_bus_write | Write entire bus output |
| ctl_bus_write_bit | Write a single bit to bus |
| ctl_bus_write_bits | Write bits to bus through a mask |
