Summary
This page is for describing the functions found in the file seq_buttons.inc in the MBSEQ v2.4a application.

Function Descriptions
SEQ_BUTTON_Handler_ChkGP1 first moves MIOS_PARAMETER1 into W, AND's W with 0xf8 and then xorlw's against “(DEFAULT_GP_DIN_SR0 - 1) « 3” which, presumably results in zero if the registers match. Perhaps the AND statement converts the button number in MIOS_PARAMETER1 into a value representing which SR it belongs to.
SEQ_BUTTON_Handler searches through mios_tables.inc for a DIN pin that matches MIOS_PARAMETER1 and then calls the appr. function
From the comments:
GP button number is stored in MIOS_PARAMETER1, button value in MIOS_PARAMETER2 (1 for released, 0 for pressed)
If the button press did come from one of the GP's then the program branches to SEQ_GP_Button in seq_gp.inc, not to be confused with SEQ_Button_GP in seq_button.inc.
