R_MTU_Read

4) R_MTU_Read

Synopsis

Read from timer channel registers.

Prototype bool R_MTU_Read(

uint8_t data1, // Channel selection

uint8_t * data2, // A pointer to the data storage location

uint16_t * data3, // A pointer to the data storage location

uint16_t * data4, // A pointer to the data storage location

uint16_t * data5, // A pointer to the data storage location

uint16_t * data6, // A pointer to the data storage location

uint16_t * data7 // A pointer to the data storage location

uint16_t * data8, // A pointer to the data storage location

uint16_t * data9 // A pointer to the data storage location

);

Description

Read any of the timer’s counter, compare or status flag registers.

[data1]

The channel number n (where n = 0 to 4).

[data2]

The status flags shall be stored in the format below.

The input capture / compare match flags A to D will be set to1 if the condition has been detected.

For n = 0, 1, 2 or 3
