Timers
When working in the cascaded mode, the cascaded TRR, TCR, and TCN should always be
referenced with 32-bit bus cycles.
7.5.2.2 TIMER GLOBAL CONFIGURATION REGISTER (TGCR). The TGCR is a 16-bit,
memory-mapped, read/write register that contains configuration parameters used by all four
timers. It allows starting and stopping any number of timers simultaneously if one bus cycle
is used to access TGCR. The TGCR is cleared by reset.

This bit is only valid if the gate function is enabled in TMR3 or TMR4.
0 = Normal Operation.
1 = Timers 3 and 4 are cascaded to form a 32-bit timer.
0 = Normal Operation.
1 = Timers 1 and 2 are cascaded to form a 32-bit timer.
0 = The corresponding timer ignores the FREEZE pin.
1 = Halt the corresponding timer if the FREEZE pin is asserted. (The FREEZE pin is
