Basic Timer1 имеет 16-bit; источником м.б. SMCLK The Basic Timer1 supplies LCD timing and low frequency time intervals. The Basic Timer1 is two independent 8-bit timers that can also be cascaded to form one 16-bit timer function.
-------------------------------------------------
BTDIV Bit 5 Basic Timer1 clock divide. This bit together with the BTSSEL bit, selects
the clock source for BTCNT2.
BTSSEL BTDIV BTCNT2 Clock Source
0 0 ACLK
0 1 ACLK/256
1 0 SMCLK
1 1 ACLK/256
-----------------------------
SMCLK: Sub-main clock. SMCLK is software selectable as XT2CLK (if
available), or DCOCLK.
------------------------------
например
у MSP430F427 DCOCLK=1 MHz
при N(DCO)=01E0h, FN_8=FN_4=FN_3=FN_2=0, D = 2; DCOPLUS= 0
