DUAL 12-BIT AUTORELOAD TIMER 4 (Cont’d)

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.

Notes:

1. DCR2/3 transfer will be 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 will be 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 set the PWM2/PWM3 frequency when

ENCNTR2 is set.

DTE DT6 DT5 DT4 DT3 DT2 DT1 DT0

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 will be at their reset state.
