Timer Registers
Each timer is controlled by a block of registers assigned to that specific timer. All timers contain an identical set of registers.
Register names for a specific instance are defined by appending the instance number to the peripheral name. For example,
the Timer Count Register for Timer 0 is TMR0_CNT while the Timer Count Register for Timer 1 is TMR1_CNT, and so on. The
MAX32660 includes three timer instances, TMR0, TMR1 and TMR2.
The base address for TMR0, TMR1 and TMR2 are as follows:
•
TMR0: 0x4001 0000
•
TMR1: 0x4001 1000
•
TMR2: 0x4001 2000
Refer to
