CLKE1_EN
This bit controls whether the output on the CLKE1 pin is enabled.
0: The output is disabled. CLKE1 is in High-Z state.
1: The output is enabled. The frequency of CLKE1 is determined by the CLKE1 bit (b2, CLKG). (default)
2
CLKE1
This bit is valid only when the CLKE1_EN bit (b3, CLKG) is ‘1’. This bit selects the clock frequency output on the CLKE1 pin.
0: 8 KHz.
1: 2.048 MHz. (default)
1
CLKT1_EN
This bit controls whether the output on the CLKT1 pin is enabled.
0: The output is disabled. CLKT1 is in High-Z state.
1: The output is enabled. The frequency of CLKT1 is determined by the CLKT1 bit (b0, CLKG). (default)
0
CLKT1
This bit is valid only when the CLKT1_EN bit (b1, CLKG) is ‘1’. This bit selects the clock frequency output on the CLKT1 pin.
0: 8 KHz.
1: 1.544 MHz. (default)
Address: 2C0H
Type: Read
Default Value: 00H

INT_CH[8:1]
These bits indicate whether there is an interrupt generated in the corresponding channel. The INT_CH[8:1] bits correspond to
channel 8 to 1 respectively.
0: No interrupt is generated or all the interrupts are cleared in the corresponding channel. (default)
1: At least one interrupt is generated in the corresponding channel.
