DUAL 12-BIT AUTORELOAD TIMER 4 (cont’d)
Bit 1 = TRAN2 Transfer Enable 2
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.
Notes:
1. DCR2/3 transfer is controlled using this bit if
ENCNTR2 bit is set.
2. This bit must not be reset by software.
Bit 0 = TRAN1 Transfer Enable 1
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.
Notes:
1. DCR0,1 transfers are always controlled using
this bit.
2. DCR2/3 transfer is controlled using this bit if
ENCNTR2 is reset.
3.This bit must not be reset by software

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
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
Note:
1. If DTE is set and DT[6:0] = 0, PWM output sig-
nals are at their reset state.
