7) R_MTU2_ReadUnit
Synopsis
Read from MTU registers.
Prototype
bool R_MTU2_ReadUnit(
uint8_t data1,
// Unit selection
uint16_t * data2,
// A pointer to the data storage location
uint8_t * data3
// A pointer to the data storage location
);
Description
Read any of the timer units’s counter registers
[data1]
The unit number n (where n = 0 to 1).
[data2]
A pointer to where the Timer Subcounter register (TCNTS) value shall be stored.
Specify PDL_NO_PTR if it is not required.
[data3]
Where the Timer Interrupt Skipping Counter register (TITCNT) value shall be stored.
