MISCELLANEOUS REGISTERS (Cont’d)
MISCELLANEOUS REGISTER 2 (MISCR2)
Read/Write
Reset Value: 0000 0000 (00h)
Caution: This register has been provided for com-
patibility with the ST72254 family only. The same
bits are available in the SPICSR register. New ap-
plications must use the SPICSR register. Do not
use both registers, this will cause the SPI to mal-
function.
Bits 7:4 = Reserved always read as 0
Bits 3 = MOD SPI Master Output Disable
This bit is set and cleared by software. When set, it
disables the SPI Master (MOSI) output signal.
0: SPI Master Output enabled.
1: SPI Master Output disabled.
Bit 2 = SOD SPI Slave Output Disable
This bit is set and cleared by software. When set it
disable the SPI Slave (MISO) output signal.
0: SPI Slave Output enabled.
1: SPI Slave Output disabled.
Bit 1 = SSM SS mode selection
This bit is set and cleared by software.
0: Normal mode - the level of the SPI SS signal is
1: I/O mode, the level of the SPI SS signal is read
Bit 0 = SSI SS internal mode
This bit replaces the SS pin of the SPI when the
SSM bit is set to 1. (see SPI description). It is set
and cleared by software.
