Table 44 Channel 0 period setting for some sampling rates (CLKCON.TICKSPD = 000)
The DSM starts immediately after DSM mode
has been enabled by setting the
T1CCTL1.CMP field. Thus, all configuration
should have been performed prior to enabling
DSM mode. Also, the Timer 1 counter should
be cleared and started just before starting the
DSM operation. A simple procedure for setting
up DSM mode should then be as follows:
1. Suspend timer 1 (T1CTL.MODE = 0)
2. Clear timer counter by writing any
value to T1CNTL, (T1CNT = 0x0000)
3. Set the sample rate by writing the
Timer 1 channel 0 count period,
T1CC0.
4. Set Timer 1 channel 0 compare mode
(T1CCTL0.MODE = 1)
5. Load first sample if available (or zero if
no sample available) into
T1CC1H:T1CC1L.
6. Set timer operation to modulo mode
(T1CTL.MODE = 2)
7. Configure the DSM by setting the
MODE and CAP fields of the T1CCT1
register.
8. Enable DSM mode
(T1CCTL1.CMP = 7)
On each Timer 1 IRQ or Timer 1 DMA trigger,
write a new sample to the T1CC1H:T1CC1L
registers. The least significant bits must be
written to T1CC1L before the most significant
bits are written to T1CC1H.
The samples written must be signed 2’s
complement values. The 2 least significant bits
will always be treated as 0, thus the effective
sample size is 14 bits.
13.3.12 Timer 1 Registers
This section describes the Timer 1 registers
that consist of the following registers:
• T1CNTH – Timer 1 Count High
• T1CNTL – Timer 1 Count Low
• T1CTL – Timer 1 Control and Status
• T1CCTLx – Timer 1 Channel x
Capture/Compare Control
• T1CCxH – Timer 1 Channel x
Capture/Compare Value High
• T1CCxL – Timer 1 Channel x
Capture/Compare Value Low
