15.3.2.4.1 7-Bit PCLRR_x Register
The 7-bit PCLRR_DSPI register is the clear output data register for PDSPIn. Figure 15-18 displays the
7-bit PCLRR_DSPI register.
15.3.2.4.2 5-Bit PCLRR_x Registers
The 5-bit PCLRR_x registers are the pin data and set data registers for PPCIBGn (PCLRR_PCIBG) and
PPCIBRn (PCLRR_PCIBR). Figure 15-19 displays the 5-bit PCLRR_x registers.
