MISCELLANEOUS REGISTERS (Cont’d)

MISCELLANEOUS REGISTER 2 (MISCR2)

Read/Write

Reset Value: 0000 0000 (00h)

Bit 7:6 = Reserved Must always be cleared

Bit 5:4 = BC[1:0] Beep control

These 2 bits select the PF1 pin beep capability.

The beep output signal is available in Active Halt

mode but has to be disabled to reduce the con-

sumption.

Bit 3:2 = Reserved Must always be cleared

Bit 1 = SSM SS mode selection

It is set and cleared by software.

0: Normal mode - SS uses information coming

from the SS pin of the SPI.

1: I/O mode, the SPI uses the information stored

into bit SSI.

Bit 0 = SSI SS internal mode

This bit replaces pin SS of the SPI when bit SSM is

set to 1. (see SPI description). It is set and cleared

by software.
