BIT
SYMBOL
FUNCTION
P2M1.7
P2S
When P2S = 1, this bit enables Schmitt trigger inputs on Port 2.
P2M1.6
P1S
When P1S = 1, this bit enables Schmitt trigger inputs on Port 1.
P2M1.5
P0S
When P0S = 1, this bit enables Schmitt trigger inputs on Port 0.
P2M1.4
ENCLK
When ENCLK is set and the 87LPC760 is configured to use the on-chip RC oscillator, a clock
output is enabled on the X2 pin (P2.0). Refer to the Oscillator section for details.
P2M1.2
T0OE
When set, the P1.2 pin is toggled whenever Timer 0 overflows. The output frequency is therefore
one half of the Timer 0 overflow rate. Refer to the Timer/Counters section for details.
P2M1.1, P2M1.0
—
These bits, along with the matching bits in the P2M2 register, control the output configuration of
P2.1 and P2.0 respectively1.

Keyboard Interrupt (KBI)
The Keyboard Interrupt function is intended primarily to allow a
single interrupt to be generated when any key is pressed on a
keyboard or keypad connected to specific pins of the P87LPC760,
as shown in Figure 14. This interrupt may be used to wake up the
CPU from Idle or Power Down modes. This feature is particularly
useful in handheld, battery powered systems that need to carefully
manage power consumption yet also need to be convenient to use.
The P87LPC760 allows any pin of port 0 to be enabled to cause this
interrupt. Port pins are enabled by the setting of bits in the KBI
register, as shown in Figure 15. The Keyboard Interrupt Flag (KBF)
in the AUXR1 register is set when any enabled pin is pulled low
while the KBI interrupt function is active. An interrupt will generated
if it has been enabled. Note that the KBF bit must be cleared by
software.
Due to human time scales and the mechanical delay associated with
keyswitch closures, the KBI feature will typically allow the interrupt
service routine to poll port 0 in order to determine which key was
pressed, even if the processor has to wake up from Power Down
mode. Refer to the section on Power Reduction Modes for details.
