Avalon-MM Interface Register Map
If the hitless bandwidth repositioning ( HBWR ) register is not enabled, the CALM1 ,
CALLEN1 , and CALMEM_DAT1 registers become reserved.
Only change the CALM0 , CALLEN0 , and CALMEM_DAT0 registers when the DISABLED
register is equal to 1, or when the CALSEL_ACT register is equal to 1. Only change the
CALM1 , CALLEN1 , and CALMEM_DAT1 registers when the DISABLED register is equal to 1, or
when the CALSEL_ACT register is equal to 0.

Description

Block ID
HBWR_EN enables the calendar select word in the status
frame.
RSFRM disables the status finite state machine. The
framing word 'b11 is sent continuously starting at the
next frame boundary. Regular behavior resumes when
this bit is cleared. The value of the register is OR ed with

RSFRM
Read write control
the ctl_ry_rsfrm input.
This bit resets to one. Therefore, you must reprogram
the calendar and clear this bit whenever the MegaCore
function is reset.
