Bits 15 to 0: Type 2 Timer/Counter Reload Register (T2Rx[15:0]). This 16-bit register holds the reload value for the timer. When oper-
ating in 16-bit mode (T2MD = 0), the full 16 bits are read/write accessible. If the dual 8-bit mode of operation is selected, the upper
byte of T2Rx is inaccessible. T2Rx reads while in the dual 8-bit mode return 00h as the high byte and writes to the upper byte of T2Rx
are blocked. A separate T2RHx register is provided to facilitate high-byte access for the dual 8-bit mode.
Note: For convenience, the lower byte of T2Rx (T2Rx[7:0]) is referred to as T2RLx. Unlike T2RHx, there is no separate T2RLx register
and the low byte is always accessed through T2Rx.
