 Description of Registers

LEDACNT (initial value: undefined) --- <Address: 0x00, Data: [D5: D0]>

LEDBCNT (initial value: undefined) --- <Address: 0x01, Data: [D5: D0]>

LEDCCNT (initial value: undefined) --- <Address: 0x02, Data: [D5: D0]>

LED current values are controlled. LEDA1/A2, LEDB1/B2 and LEDC1/C2 are controlled through the registers

LEDACNT, LEDBCNT and LEDCCNT respectively, and the current setting can be switched every 2 channels.

For the current setting value in each register setting, refer to

‘LED Current Setting Table’ on page 9.

LEDA1 (initial value: ‘0) --- <Address: 0x03, Data: D0>

LEDA2 (initial value: ‘0) --- <Address: 0x03, Data: D1>

LEDB1 (initial value: ‘0) --- <Address: 0x03, Data: D2>

LEDB2 (initial value: ‘0) --- <Address: 0x03, Data: D3>

LEDC1 (initial value: ‘0) --- <Address: 0x03, Data: D4>

LEDC2 (initial value: ‘0) --- <Address: 0x03, Data: D5>

The ON/OFF setting of each LED driver channel is as follows:

’0’: OFF

‘1’ :ON

FREQCNT (initial value:

‘0) --- <Address: 0x03, Data: D6>

The switching frequency of a charge pump is set as follows:

’0’: 1MHz

‘1’: 250kHz
