27.5.9 I2C Queue command reg (HW_I2C_QUEUECMD)
The I2C Command Register accepts commands that are to be queued up for later execution
in PIO queue mode.
HW_I2C_QUEUECMD: 0x080
HW_I2C_QUEUECMD_SET: 0x084
HW_I2C_QUEUECMD_CLR: 0x088
HW_I2C_QUEUECMD_TOG: 0x08C
This register is either written by the CPU to queue up I2C transaction commands for later
execution.
