When MCT is enabled, a read from MCTH causes the value in MCTL to be stored in a
temporary holding register. A read from MCTL returns this temporary register when MCT
is enabled. When MCT is disabled, reads from MCTL read the register directory. 
The MCT High and Low byte registers are not reset when TEN = 0.
MCTH and MCTL—MCT High and Low Bytes
These 2 bytes, {MCTH[7:0], MCTL[7:0]}, contain the current 16-bit MCT count value.
The MCT Reload High and Low Byte (MCTRH and MCTRL) registers (see
Table
writes to this address update the register on the next clock cycle. When TEN = 1 writes to
this register are buffered and transferred into the register when the counter reaches the end
of the count cycle.
