CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Telephone Function)

CTMUT: Transmit mute control (FF18H•D0)

Controls the transmit mute.

When "1" is written: Transmit mute output

When "0" is written: Low level output on XTMUTE (R10) terminal

Reading: Valid

When "0" is written to the CTMUTE register, the XTMUTE (R10) terminal is pulled down to Low (VSS) level to mute the transmit line.

When the CTMUTE register is set to "1", the XTMUTE (R10) terminal is controlled by the hardware and will be Low (VSS) level during a dialing pulse cycle, flash cycle, dialing tone cycle or a hold-line cycle. At initial reset, this register is set to "1".

HSON: Hook switch ON/OFF (FF18H•D0)

Controls the hook switch.

When "1" is written: Hook OFF

When "0" is written: Hook ON

Reading: Valid

When the HSON register is set to "1", the DP terminal goes High (VDD) level and the hook switch goes to off-hook status.

At initial reset, this register is set to "0".

CTO: Continuous output tone selection (FF16H•D3)

Selects the tone duration time to continuous output or not.

When "1" is written: Continuous

When "0" is written: 94 msec

Reading: Valid

This register is used to decide the tone duration time. The minimum value of tone duration time is 94 msec.

When the CTO register is set to "1", a tone signal will be output until the CTO register is changed to "0". If the period (CTO is changed from "1" to "0"), that is controlled by the CTO register, is less than 94 msec, the duration time will be prolonged to 94 msec.

When the CTO register is set to "0", a tone signal will be output with the minimum time (94 msec). This setting is valid only for tone mode.

At initial reset, this register is set to "0".

EID: Interrupt mask register (FFE9H•D0)

Enables or disables the generation of an interrupt for the CPU.

When "1" is written: Enabled

When "0" is written: Disabled

Reading: Valid

EID is the interrupt mask register corresponding to the dialing interrupt factor. Interrupts set to "1" are enabled and interrupts set to "0" are disabled.

At initial reset, this register is set to "0".
