7. Page 3-19, Register 3-1: MODCON:
Modulo and Bit-Reversed Addressing
Control Register, bit 7-4
On page 3-19, Register 3-1: MODCON: Modulo
and Bit-Reversed Addressing Control Register,
the description for bit4 through bit7 should be
modified as follows. All other bit definitions do not
change and hence are not described:
Register 3-1: MODCON: Modulo and Bit-Reversed Addressing Control Register
Upper Byte:
R/W-0 R/W-0 U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0
XMODEN YMODEN — — BWM<3:0>
bit 15 bit 8
Lower Byte:
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
YWM<3:0>
XWM<3:0>
bit 7 bit 0
bit 7-4 YWM<3:0>: Y AGU W Register Select for Modulo Addressing bits
1111 = Modulo addressing disabled
1110 = W14 selected for modulo addressing
1101 = W13 selected for modulo addressing
| |
0000 = W0 selected for modulo addressing
Note: A write to the MODCON register should not be followed by an instruction that performs an
indirect read operation using a W register. Unexpected results may occur. Some instructions
perform an implicit indirect read. These are: POP, RETURN, RETFIE, RETLW and ULNK.
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
