TM2CON0 is a special function (SFR) to control a timer 2.
Rewrite TM2CON0 while the timer 2 is stopped (T2STAT of the TM2CON1 register is “0”).
[Description of Bits]
Initial value
TM2CON0
In 16-bit timer mode, timer 2 and timer 3 are connected and they operate as a 16-bit timer.
The T2CS1 and T2CS0 bits are used for selecting the operation clock of timer 2. LSCLK, HTBCLK, or the external
clock (P44/T02P0CK) can be selected by these bits.
The T23MFM bit and T23M16 bit is used for selecting the operating mode of timer 2 and timer 3..
In 8-bit timer mode, each of timer 0 and timer 1 operates independently as a 8-bit timer.
In 16-bit timer mode, timer 3 is incremented by a timer 2 overflow signal. A timer 2 interrupt (TM2INT) is not
generated.
In 16-bit timer frequency measurement mode, timer 2 and timer 3 are connected and they operate as a 16-bit clock
counter to measure the frequency. A timer 2 interrupt (TM2INT) is not generated.
The T2FMA7 bit ~T2FMA4 bit shows the LSI has the frequency measurement mode.
Those bits are read-only and always return 1010b on ML610Q421/ML610Q422.
