LPC1311/13/42/43
32-bit ARM Cortex-M3 microcontroller
10.7 SSP0/1 interface
Remark: The SSP1 interface is available on the LPC1313FBD48/01 only.
[1]
Tcy(clk) = (SSPCLKDIV
× (1 + SCR) × CPSDVSR) / fmain. The clock cycle time derived from the SPI bit rate Tcy(clk) is a function of the
main clock frequency fmain, the SSP peripheral clock divider (SSPCLKDIV), the SSP SCR parameter (specified in the SSP0CR0
register), and the SSP CPSDVSR parameter (specified in the SSP clock prescale register).

Tamb =

Tcy(clk) = 12
× Tcy(PCLK).
