Arguments
- const Bit[4] B1: Bank to retrieve lower two bytes of number, or zero if number is given as a literal value.
- const Bit[4] B2: Bank to retrieve higher two bytes of number, or zero if number is given as a literal value.
- const UByte W: Window ID whose numerical display will be set.
- const ULong N: A four-byte number to set the numerical display. If B1 or B2 are non-zero, this value is split into two two-byte values, indicating the address to find the number value in banks B1 and B2, respectively.
- const UByte C: The number of digits to display, from 1 to 8.
Description
Sets the numerical display, as found in the WSPCL opcode. The number may be set with a specified value or retrieved from two 16-bit values, and the number of digits to show is specified with C. Unlike the other special window setting function, STTIM, the WINDOW ID must be given for this opcode.
If the value does not fit in the specified number of digits for the display, the higher units are not displayed.
