This commit introduces three timer driver changes: * Export the definitions of the timer structures to a detailed header at <gint/mpu/tmu.h>, and re-use them in the driver. This integration is still limited as the driver keeps its own address definitions and event codes. * Clean the timer stop routine that is used in the interrupt handler. Up until now the interrupt handler would only stop TSTR, which is not enough to cleanly leave the timer (need TCOR=TCNT=-1) and is not even sound with respect to gint's semantics as UNIE stays enabled so the timer is not made available again. The interrupt handler now calls into C code when the timer stop condition is met (callback returns non-zero) to keep this clean. This unsurprisingly solves problems that occurred in certain situations when a timer was used repeatedly. * Expose timer addresses using a timer_address() function, compensating for the lack of address definitions in <gint/mpu/tmu.h>. This interface is likely to evolve in the future to better integrate the address in the MPU headers and move them out of the driver. |
