27.6 TSC registers
Refer to Section 1.1 on page 34 of the reference manual for a list of abbreviations used in
register descriptions.
The peripheral registers can be accessed by words (32-bit).

Bits 31:28 CTPH[3:0]: Charge transfer pulse high
These bits are set and cleared by software. They define the duration of the high state of the
charge transfer pulse (charge of C
X
).
0000: 1x t
PGCLK
0001: 2x t
PGCLK
...
1111: 16x t
PGCLK
Note: These bits must not be modified when an acquisition is on-going.
Bits 27:24 CTPL[3:0]: Charge transfer pulse low
These bits are set and cleared by software. They define the duration of the low state of the
charge transfer pulse (transfer of charge from C
X
to C
S
).
0000: 1x t

Note: These bits must not be modified when an acquisition is on-going.
Bits 23:17 SSD[6:0]: Spread spectrum deviation
These bits are set and cleared by software. They define the spread spectrum deviation which
consists in adding a variable number of period at f
SSCLK
to the charge transfer pulse high
state.

Note: These bits must not be modified when an acquisition is on-going.
Bit 16 SSE: Spread spectrum enable
This bit is set and cleared by software to enable/disable the spread spectrum feature.
0: Spread spectrum disabled
1: Spread spectrum enabled
Note: This bit must not be modified when an acquisition is on-going.
