Legend: x = unknown value on Reset; — = unimplemented, read as ‘0’. Reset values are shown in hexadecimal.
Note 1:
All registers in this table except SPIxBUF have corresponding CLR, SET and INV registers at their virtual addresses, plus offsets of 0x4, 0x8 and 0xC, respectively. See Section 11.2 “CLR, SET and INV
Registers” for more information.
