Timer Port Pin Allocation
Asserting TMR3_OC_CTL1[MAST_MODE] selects MASTER MODE for all OUTPUT
COMPARE events and sets output 0 as the master. As a result, outputs 1, 2, and 3 are
caused to disregard output-specific configuration and comparison values and instead
mimic the current settings for output 0.
The OCx bits in the TMR3_IIR register are set whenever the corresponding timer com-
pares occur. TMR3_IER[IRQ_OCx_EN] allows the compare event to generate a timer
interrupt.
The eZ80F91 device timers interface to the outside world via Ports A and B. These
ports are also used for GPIO as well as other assorted functions.
