/*
* soft_i2c.c
*
* looked at random i2c code, used as inspiration, and wrote some
* garbage for CH59x.
* looked at random code and fixed it up for CH59x.
*
* i2c hardware peripheral on CH59x is shared with debug pins.
* i2c hw is also not attached to DMA. while using the peripheral
* even in interrupt mode would result in higher speeds and less
* power consumption, living without debug is worse.
* also, i2c on CH59x is not attached to DMA. while using the
* peripheral would result in higher speeds and less power usage,
* living without debug is worse. maybe I'll use hw i2c later.
*
* quirks and features:
* - this implementation is blocking.
* - clock stretching is supported, and somewhat tested
*
* known good settings:
* CYCLES_TO_HI = 5, CYCLES_TO_LOW = 2: ~400-500kHz
* CYCLES_TO_HI = 2, CYCLES_TO_LOW = 0: ~650KHz
* - partial clock stretching is supported
* (only during start of write, and within read phase).
* - timings likely haven't been tested so long as this message exists.
