10.2.12 Timer 2 Control Register 0 (TM2CON0)
• T2CS1, T2CS0 (bits 1, 0)
• T23MFM, T23M16 (bit 3, 2)
• T2FMA7~T2FMA4 (bit 7~4)
ML610Q415 does not have the frequency measurement mode. The T23MFM bit is read-only and always return “0”
despite of writing any data on the ML610Q415.
Address: 0F03AH
Access: R/W
Access size: 8 bits
Initial value: 00H(ML610Q415), 0A0H(ML610Q411/ML610Q412)
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”).

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 the initial value despite of writing any data.
