Timer Interface Module A (TIMA)
I/O Registers
prescaler select bits, PS[2:0] (see TIMA Status and Control Register).
The minimum TCLK pulse width, TCLK_LMIN or TCLK_HMIN, is:
b----u---s-----f--r--e--1-q---u----e---n---c---y-- ^{+ tSU}
The maximum TCLK frequency is the least: 4 MHz or bus frequency ÷ 2.
PTD6/ATD14/TACLK is available as a general-purpose I/O pin or ADC
channel when not used as the TIMA clock input. When the
PTD6/ATD14/TACLK pin is the TIMA clock input, it is an input regardless
of the state of the DDRD6 bit in data direction register D.
22.8.2 TIMA Channel I/O Pins (PTF3/TACH5–PTF0/TACH2 and
PTE3/TACH1–PTE2/TACH0)
Each channel I/O pin is programmable independently as an input
capture pin or an output compare pin. PTE2/TACH0, PTF0/TACH2 and
PTF2/TACH4 can be configured as buffered output compare or buffered
PWM pins.
22.9 I/O Registers
These I/O registers control and monitor TIMA operation:
• TIMA status and control register (TASC)
• TIMA control registers (TACNTH–TACNTL)
• TIMA counter modulo registers (TAMODH–TAMODL)
• TIMA channel status and control registers (TASC0, TASC1,
TASC2, TASC3, TASC4 and TASC5)
• TIMA channel registers (TACH0H–TACH0L, TACH1H–TACH1L,
TACH2H–TACH2L, TACH3H–TACH3L, TACH4H–TACH4L and
TACH5H–TACH5L)
