There are also additional ten timers in the MCU domain which are meant for MCU firmware usage and hence marked reserved by default. The odd numbered timers have the option of being cascaded to even timers to create a 64 bit non-atomic counter which is racy in simple usage, hence the clock muxes are explicitly setup to individual 32 bit counters driven off system crystal (HFOSC) as default. These instantiation differs from J7200 and other SoCs with the device IDs and clocks involved for muxing.
