6.6 SSPn Interrupt Mask Set/Clear Register (SSP0IMSC - 0xE006 8014,
0xE003 000C)
This read-only register reflects the current status of the SSP controller.
Table 474: SSPn Status Register (SSP0SR - address 0xE006 800C, SSP1SR - 0xE003 000C)
- 0xE003 0010)
This register controls the factor by which the Prescaler divides the SSP peripheral clock
SSP_PCLK to yield the prescaler clock that is, in turn, divided by the SCR factor in
SSPnCR0, to determine the bit clock.
Table 475: SSPn Clock Prescale Register (SSP0CPSR - address 0xE006 8010, SSP1CPSR -
Important: the SSPnCPSR value must be properly initialized or the SSP controller will not
be able to transmit data correctly.
In Slave mode, the SSP clock rate provided by the master must not exceed 1/12 of the
SSP peripheral clock selected in

In master mode, CPSDVSR
SSP1IMSC - 0xE003 0014)
This register controls whether each of the four possible interrupt conditions in the SSP
controller are enabled. Note that ARM uses the word “masked” in the opposite sense from
classic computer terminology, in which “masked” meant “disabled”. ARM uses the word
“masked” to mean “enabled”. To avoid confusion we will not use the word “masked”.
