TSC2301 KEYPAD REGISTERS
Keypad Control Register (Page 1, Address 01H)
TSC2301
SLAS371D – SEPTEMBER 2002 – REVISED AUGUST 2004
The keypad scanner hardware in the TSC2301 is controlled by two registers: the keypad control register and the
keypad mask register. The keypad control register controls general keypad functions such as scanning and
de-bouncing, while the keypad mask register allows you to mask certain keys from being detected at all.
The Keypad Control register is formatted as follows:
Bit 15
Bit 14
Bit 13
Bit 12
Bit 11
Bit 10
Bit 9
Bit 8
Bit 7
Bit 6

Bit 15 — STC
Keypad Status. This bit reflects the operation of the KBIRQ pin, with inverted logic. This bit goes high when a key
is pressed and debounced. The default value for this bit is 0.

Value
Description
0
No keys are pressed (default)
1
Key pressed and debounced
Bit 14 — SCS
Keypad Scan Status. When reading, this bit indicates if the scanner or de-bouncer is busy. Writing a 0 to this bit
causes keypad scans to continue until either the key is lifted or the process is stopped. Continuous scans can be
stopped by writing a 1 to this bit. This immediately halts a conversion (even if a key is still down). The default
value for this bit when read is 1.

Bits [13:11] — KBDB2-KBDB0
Keypad De-bounce Control. These bits set the length of the de-bounce time for the keypad, as shown in
Table 22. The default setting is a 2-ms de-bounce time (000).
