Type	Name
uint16_t	address DCS-BIOS output address (A_4E_C_* from A4EC_OutputIds.h )
uint16_t	mask field mask (A_4E_C_*_AM); 0xFFFF for whole-word sources
uint8_t	mul = 1 displayed value per position (5 for the ARC-51 50 kHz drum)
uint8_t	nDigits digits this address encodes (1 for APN153, 2 for ARC-51 groups)
int16_t	offset = 0 added after mul (22 for the ARC-51 10 MHz group, 29 for ALT_ADJ)
uint8_t	place least-significant digit column this source writes (0 = rightmost)
uint16_t	steps = 0 positions across the range; 0 ⇒ 10^nDigits (a plain drum digit)

Detailed Description

Note:

Populate address / mask from the A_4E_C_* and A_4E_C_*_AM constants in A4EC_OutputIds.h. The masked value (0..mask) is scaled to nDigits decimal digits: digits = round((value & mask) / mask * (10^nDigits − 1)); each of those nDigits digits is spliced into the readout's combined number starting at place (0 = least-significant column).
