Version 3.x
TIMR Timer Register (READ/WRITE) is unchanged. However the input to the timer
function can be optionally selected to be XTAL/4 in master clock mode by setting
CCR0:MCE = ‘1’ and CCR4:MCK4 = ‘1’.
VALUE …
Non Master Clock Mode (CCR0:MCE = ‘0’)
Master Clock Mode (CCR0:MCE = ‘1’)
With CCR4:MCK4 =’1’ in master clock mode, XTAL clock divide-by-4 is fed to the timer
block. The XTAL clock feeds the baud rate generator which is used to select the transmit
and received baud rate and generates the 16- oversampling clock. By this means, a
XTAL clock of 30 MHz can be used while maintaining the core logic’s clock operation
limit of 10 MHz.

(5 bits) sets the time period
With CCR4:MCK4 = ‘0’ and default condition, the timer value is
given by the equation
t
where
– k is the timer resolution factor which is either 32 768
– TCP is the clock period of the Timer Clock.
Timer Clock Period (TCP) = Transmit Clock Period
if CCR4:MCK4 = ‘0’ (Reset state)
Timer Clock Period (TCP) = XTAL Clock Period
if CCR4:MCK4 = ‘1’
Timer Clock Period (TCP) = XTAL Clock Period/4
(3 bits) The CNT function is unchanged.
