9.5.5 Timer Counter Register
M68HC11E Family — Rev. 3.2
MOTOROLA
Register name: Timer Counter Register (High)
Register name: Timer Counter Register (Low)
The 16-bit read-only TCNT register contains the prescaled value of the
16-bit timer. A full counter read addresses the most significant byte
(MSB) first. A read of this address causes the least significant byte (LSB)
to be latched into a buffer for the next CPU cycle so that a double-byte
read returns the full 16-bit state of the counter at the time of the MSB
read cycle.
