11.14.2 8/16-bit Composite Timer Status Control Register 1
(Tn0CR1/Tn1CR1)
The 8/16-bit composite timer status control register 1 (Tn0CR1/Tn1CR1)
controls the interrupt flag, timer output, and timer operations. Tn0CR1 and
Tn1CR1 registers correspond to timers n0 and n1 respectively.

Initial value 0
■ Register Functions
[bit7] STA: Timer operation enable bit
This bit enables or stops the timer operation.
Writing "0": stops the timer operation and sets the count value to "0x00".
• With the PWM timer function (variable-cycle mode) in use (Tn0CR0/Tn1CR0:F[3:0] = 0b0100), the STA bit
in either the Tn0CR1 (timer n0) or the Tn1CR1 (timer n1) register can be used to enable or disable the timer
operation. If the STA bit in one of the registers is set to "0", the STA bit in the other one is automatically set
to the same value.
• In 16-bit operation (TMCRn:MOD = 1), use the STA bit in the Tn0CR1 (timer n0) register to enable or disable
timer operation. If the STA bit of one of the timers is set to "0", the STA bit in the other one is automatically
set to the same value.
Writing "1": starts the timer operation from the count value "0x00".
• Before setting this bit to "1", set the count clock select bits (Tn0CR0/Tn1CR0:C[2:0]), timer operation select
bits (Tn0CR0/Tn1CR0:F[3:0]), timer output initial value bit (Tn0CR1/Tn1CR1:SO), 16-bit mode enable bit
(TMCRn:MOD), and filter function select bits (TMCRn:FEn1, FEn0).
