19.7 Registers

16-bit PPG Status Control Register (Upper)

The 16-bit PPG status control register (upper) enables or disables the 16-bit

PPG timer, and controls the software trigger, operating mode, operating clock

and output mask.

■ Register Configuration

Initial value

■ Register Functions

[bit7] CNTE: Timber enable bit

This bit enables or stops the 16-bit PPG timer operation.

When "0" is written to this bit, the 16-bit PPG timer operation stops immediately and the PPGn output goes

to the initial level ("L" output if OSEL is "0"; "H" output if OSEL is "1").

When "1" is written to this bit, the 16-bit PPG timer operation is enabled and the 16-bit PPG timer goes to

standby to wait for a trigger.

[bit6] STRG: Software trigger bit

This bit starts the 16-bit PPG timer by software.

With the CNTE bit set to "1", writing "1" to the STRG bit starts the 16-bit PPG timer.

[bit5] MDSE: Mode select bit

This bit selects the operating mode of the 16-bit PPG timer.

Note: While the 16-bit PPG timer is in operation, modifying the setting of this bit is prohibited.

Stops the 16-bit PPG timer operation.

Enables the 16-bit PPG timer operation.

The read value is always "0".

Has no effect on operation.

Generates a software trigger.

One-shot mode
