EM78P372K

8-bit Microcontroller

Product Specification (V1.4) 05.11.2016

 33

(This specification is subject to change without prior notice)

Bit 3 (DEADT2E): Enable dead-time function for PWM2 and /PWM2 (for dual PWM)

0: Disable (default)

1: Enable

Bit 2 (DEADT1E): Enable dead-time function for PWM1 and /PWM1 (for dual PWM)

0: Disable (default)

1: Enable

Bits 1~0 (DEADTP1~DEADTP0): Dead-time prescaler

DEADTP1

DEADTP0

Prescale

1:1 (default)

1:2

1:4

1:8

NOTE

The dead time function is only for dual PWM. If used in single PWM function

(not dual PWM), the dead time function is always disabled.

7.2.17 IOCA1 (DeadTR: Dead Time Register)

Bit 7

Bit 6

Bit 5

Bit 4

Bit 3

Bit 2

Bit 1

Bit 0

DEADTR7

DEADTR6

DEADTR5

DEADTR4

DEADTR3

DEADTR2

DEADTR1

DEADTR0

R/W-0

Bits 7~0 (DEADTR7~0): The content of the register is dead-time.

Note

The value in the dead-time register must be less than the value in the duty

cycle register in order to prevent unexpected behavior on both of PWM

outputs.

7.2.18 IOCF1 (Pull-high Control Register)

Bit 7

Bit 6

Bit 5

Bit 4

Bit 3

Bit 2

Bit 1

Bit 0

/PH67

/PH65

/PH64

/PH63

/PH62

/PH61

/PH60

Note: The IOCD0 register is both readable and writable.

Bit 7 (/PH67): Control bit used to enable pull-high of the P67 pin.

0 : Enable internal pull-high

1 : Disable internal pull-high
