LCD Drivers (71M6541D/F)
With a maximum of 35 LCD driver pins available, the 71M6541D/F is capable of driving up to 6 x 35 = 210
pixels of an LCD display when using the 6 x multiplex mode. At eight pixels per digit, this corresponds to
26 digits.
LCD segment data is written to the LCD_SEGn[5:0] I/O RAM registers as described in 2.5.8.2 and 2.5.8.3.
SEG46 through SEG50 cannot be configured as DIO pins. Display data for these pins are written to I/O
RAM registers LCD_SEG46[5:0] through LCD_SEG50[5:0] (see Table 58). When the ICE_E pin is pulled
high, it overrides the SEG functionality, and pins E_RXTX/SEG48, E_TCLK/SEG49 and E_RST/SEG50
function as ICE interface pins.
LCD_MAP[46] and LCD_MAP[47] (I/O RAM 0x2406[6] and 0x2407[7]) must be set to 1 in order to permit
TMUX2OUT/SEG46 and TMUXOUT/SEG47 to operate as SEG drivers, otherwise. If LCD_MAP[46] and
LCD_MAP[47] are 0, these pins operate as TMU2XOUT and TMUXOUT (see 2.5.12 Test Ports
