4) 2)
|
||
|
|
|
||
|
|
1) not stricty related to some register
|
||
|
|
aka MCS1
|
||
|
|
bit 0: ? always 1
|
||
|
|
bit 1: oscillator high gain
|
||
|
|
bit 2: EPWM push-pull enabled
|
||
|
|
bit 3: p2.0 state after boot
|
||
|
|
bit 4: TXD signal source from RXD
|
||
|
|
bit 5: p3.7 push-pull enabled
|
||
|
|
bit 6: UART1 remap enabled
|
||
|
|
bit 7: long power-on reset delay
|
||
|
|
|
||
|
|
2) not strictly related to some register
|
||
|
|
aka MCS4
|
||
|
|
eeprom size / code space upper limit (in pages)
|
||
|
|
only seems to apply to devices with max. flash size
|
||
|
|
e.g. fe -> 63.5K, e0 -> 56K
|
||
|
|
|
||
|
|
3) like RSTCFG? inverted?
|
||
|
|
aka MCS2
|
||
|
|
bit 0: LVD0
|
||
|
|
bit 1: LVD1
|
||
|
|
bit 2: ? always 1
|
||
|
|
bit 3: ? always 1
|
||
|
|
bit 4: ~reset pin enabled
|
||
|
|
bit 5: ? always 1
|
||
|
|
bit 6: ~enable lvd reset
|
||
|
|
bit 7: ? always 1
|
||
|
|
|
||
|
|
LVD:
|
||
|
|
2.20V -> 0xbf
|
||
|
|
2.40V -> 0xbe
|
||
|
|
2.70V -> 0xbd
|
||
|
|
3.00V -> 0xbc
|
||
|
|
|
||
|
|
4) like WDT_CONTR
|
||
|
|
aka MCS3
|
||
|
|
bit 0: WDPS0
|
||
|
|
bit 1: WDPS1
|
||
|
|
bit 2: WDPS2
|
||
|
|
bit 3: ~stop wdt in idle
|
||
|
|
bit 4: ? always 1
|
||
|
|
bit 5: ~enable wdt on por
|
||
|
|
bit 6: ? always 1
|
||
|
|
bit 7: ? always 1
|
||
|
|
|
||
|
|
WDPS like in datasheet
|
||
|
|
|
||
|
|
5)
|
||
|
|
aka MCS0
|
||
|
|
bit 0: ? ~BSLD / bootloader enabled
|
||
|
|
bit 1: erase eeprom enabled
|
||
|
|
bit 2: ?
|
||
|
|
bit 3: ?
|
||
|
|
bit 4: ?
|
||
|
|
bit 5: ?
|
||
|
|
bit 6: ?
|
||
|
|
bit 7: ?
