Timer4 - 0x8081_0060 - Read Only
0x0000_0000
This read-only register contains the low word of the time stamp debug timer
(Timer4). When this register is read, the high byte of the Timer4 counter is
saved in the Timer4ValueHigh register.
Value:
Timer4 - 0x8081_0064 - Read/Write
0x0000_0000
This is a 9-bit read/write register.
Enable is the only bit that matters during a register write. When set to “1”, the
timer is enabled and begins to count upwards. When set to 0, the debug timer
registers are cleared to all zeros and the timer stops counting
Timer4ValueHigh is a read-only value and contains the high byte of the Timer4
counter. Note that the Timer4ValueLow register must first be read to store the
high byte of the TC4 in Timer4ValueHigh register.
