CXD2053AM/AS

5-2. Bus-free mode

The CXD2053AM/AS can be operated without using the I2C bus when Pin 19 (MCON) is set to 0 and the IC is

switched to bus-free mode.

In this case, the contents normally set by the I2C are fixed to the values below.

Also, only the two functions listed in the table below can be switched by Pins 15 (SCL) and 16 (SDA).

Bit

Name

Description

bit 7 MSB ED2FSC

Directly controlled by Pin 16 (SDA).

The unmodified SDA pin level becomes ED2FSC.

bit 6

ED2RES ED2RES = 0

bit 5

bit 4

EDDEC1 bit5 = 0, bit4 = 1.

bit 3

bit 2

EDDEC2

Directly controlled by Pin 15 (SCL).

When SCL = 0, bit 3 = 0 and bit 2 = 1. When SCL = 1, bit 3 = 1 and bit 2 = 0.

bit 1

VBLNJ1 VBLNJ1 = 0

bit 0 LSB VBRES VBRES = 0

bit 7 MSB AWRES AWRES = 0

bit 6

INST

INST = 0

bit 5

bit 4

bit 3

No Use

and TEST

All 0

bit 2

bit 1

UPAREA UPAREA = 0

bit 0 LSB PAL

PAL = 0 Fixed to 525/60 mode.
