7.3 Timer Registers
The following four types of registers are used for timer control.
(1) Timer data registers
(TM0DL, TM0DH, TM1DL, TM1DH, TM2DL, TM2DH, TM3DL, TM3DH)
(2) Timer counter registers
(TM0CL, TM0CH, TM1CL, TM1CH, TM2CL, TM2CH, TM3CL, TM3CH)
(3) Timer control registers
(TM0CON0, TM0CON1, TM1CON0, TM1CON1, TM2CON0, TM2CON1, TM3CON0, TM3CON1)
(4) Timer status registers
(TM0STAT, TM1STAT, TM2STAT, TM3STAT)
The registers are described below for each type.
(1) Timer data registers
(TM0DL, TM0DH, TM1DL, TM1DH, TM2DL, TM2DH, TM3DL, TM3DH)
•
During the auto-reload mode, timer data registers store the reload values.
•
During the capture mode, timer data registers store the capture data.
Writing to a timer data register causes the contents of the timer counter register to be transferred to the
timer data register.
•
At system reset, all valid bits are cleared to “0”.
•
Note regarding register values:
When a value is written to any timer counter register, the same value is also written to the corresponding
timer data register.
However, when writing to a timer data register, the same value is not written to the corresponding timer
counter register.
