DUAL 12-BIT AUTORELOAD TIMER 3 (cont’d)
Bit 4 = OVFIE2 Overflow interrupt 2 enable
This bit is read/write by software and controls the
overflow interrupt of counter2.
0: Overflow interrupt disabled
1: Overflow interrupt enabled
Bit 3 = OVF2 Overflow Flag.
This bit is set by hardware and cleared by software
by reading the ATCSR2 register. It indicates the
transition of the counter2 from FFFh to ATR2 val-
ue.
0: No counter overflow occurred
1: Counter overflow occurred
Bit 2 = ENCNTR2 Enable counter2
This bit is read/write by software and switches the
second counter CNTR2. If this bit is set, PWM2
and PWM3 will be generated using CNTR2.
0: CNTR2 stopped
1: CNTR2 starts running
Bit 1 = TRAN2 Transfer enable2
This bit is read/write by software, cleared by hard-
ware after each completed transfer and set by
hardware after reset. It controls the transfers on
CNTR2.
It allows the value of the Preload DCRx registers
to be transferred to the Active DCRx registers after
the next overflow event.
The OPx bits are transferred to the shadow OPx
bits in the same way.
(Only DCR2/DCR3 can be controlled with this bit)
Bit 0 = TRAN1 Transfer enable1
This bit is read/write by software, cleared by hard-
ware after each completed transfer and set by
hardware after reset. It controls the transfers on
CNTR1. It allows the value of the Preload DCRx
registers to be transferred to the Active DCRx reg-
isters after the next overflow event.
The OPx bits are transferred to the shadow OPx
bits in the same way.
AUTORELOAD REGISTER 2 HIGH (ATR2H)
Read / Write
Reset Value: 0000 0000 (00h)
AUTORELOAD REGISTER 2 LOW (ATR2L)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 11:0 = ATR2[11:0] Autoreload Register 2
This is a 12-bit register which is written by soft-
ware. The ATR2 register value is automatically
loaded into the upcounter CNTR2 when an over-
flow of CNTR2 occurs. The register value is used
to
set
the
PWM2/PWM3
frequency
when
ENCNTR2 is set.
DEAD TIME GENERATOR REGISTER (DTGR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = DTE Dead Time Enable
This bit is read/write by software. It enables a dead
time generation on PWM0/PWM1.
0: No dead time insertion
1: Dead time insertion enabled
Bits 6:0 = DT[6:0] Dead Time Value
These bits are read/write by software. They define
the dead time inserted between PWM0/PWM1.
Dead time is calculated as follows:
Dead Time = DT[6:0] x Tcounter1
